About This Book

An illustrated field-guide style compendium that surveys common wildflowers by family, providing concise descriptions of flower, leaf, and root forms, habitat preferences, and flowering seasons; it explains identification features, plant reproductive adaptations, and common names and classifications, and includes lists of species with brief notes on appearance, growth habit, and where to find them, aiming to deepen practical appreciation and facilitate accurate identification for amateur naturalists.

Flowers—Bright yellow, papilionaceous, about ½ in. long, on short pedicels, in numerous but few flowered terminal racemes. Calyx light green, 4 or 5-toothed; corolla of 5 oblong petals, the standard erect, the keel enclosing 10 incurved stamens and 1 pistil. Stem: Smooth, branched, 2 to 4 ft. high. Leaves: Compounded of 3 ovate leaflets. Fruit: A many-seeded round or egg-shaped pod tipped with the awl-shaped style.

Preferred Habitat—Dry, sandy soil.

Flowering Season—June–September.

Distribution—Maine and Minnesota to the Gulf states.

Dark grayish green, clover-like leaves, and small, bright yellow flowers growing in loose clusters at the ends of the branches of a bushy little plant, are so commonly met with they need little description. A relative, the true indigo-bearer, a native of Asia, once commonly grown in the Southern states when slavery made competition with Oriental labor possible, has locally escaped and become naturalized. But the false species, although, as Doctor Gray says, it yields “a poor sort of indigo,” yields a most valuable medicine employed by the homoeopathists in malarial fevers. The plant turns black in drying. As in the case of other papilionaceous blossoms, bees are the visitors best adapted to fertilize the flowers. When we see the little, sleepy, dusky-winged butterfly (Thanaos brizo) around the plant we may know she is there only to lay eggs, that the larvae and caterpillars may find their favorite food at hand on waking into life.

Wild Lupine; Old Maid’s Bonnets; Wild Pea; Sun Dial
Lupinus perennis

Flowers—Vivid blue, very rarely pink or white, butterfly-shaped; corolla consisting of standard, wings, and keel; about ½ in. long, borne in a long raceme at end of stem; calyx 2-lipped, deeply toothed. Stem: Erect, branching, leafy, 1 to 2 ft. high. Leaves: Palmate, compounded of from 7 to 11 (usually 8) leaflets. Fruit: A broad, flat, very hairy pod, 1½ in. long, and containing 4 or 5 seeds.

Preferred Habitat—Dry, sandy places, banks, and hillsides.

Flowering Season—May–June.

Distribution—United States east of Mississippi, and eastern Canada.

Farmers once thought that this plant preyed upon the fertility of their soil, as we see in the derivation of its name, from lupus, a wolf; whereas the lupine contents itself with sterile waste land no one should grudge it—steep, gravelly banks, railroad tracks, exposed sunny hills, where even it must often burn out under fierce sunshine did not its root penetrate to surprising depths. It spreads far and wide in thrifty colonies, reflecting the vivid color of June skies, until, as Thoreau says, “the earth is blued with it.”

The lupine is another of those interesting plants which go to sleep at night. Some members of the genus erect one half of the leaf and droop the other half until it becomes a vertical instead of the horizontal star it is by day. Frequently the leaflets rotate as much as 90 degrees on their own axes. Some lupines fold their leaflets, not at night only, but during the day also there is more or less movement in the leaves. Sun dial, a popular name for the wild lupine, has reference to this peculiarity. The leaf of our species shuts downward around its stem umbrella fashion, or the leaflets are erected to prevent the chilling which comes to horizontal surfaces by radiation, some scientists think. “That the sleep movements of leaves are in some manner of high importance to the plants which exhibit them,” says Darwin, “few will dispute who have observed how complex they sometimes are.”

Common Red, Purple, Meadow, or Honeysuckle Clover
Trifolium pratense

Flowers—Magenta, pink, or rarely whitish, sweet-scented, the tubular corollas set in dense round, oval, or egg-shaped heads about 1 in. long, and seated in a sparingly hairy calyx. Stem: 6 in. to 2 ft. high, branching, reclining, or erect, more or less hairy. Leaves: On long petioles, commonly compounded of 3, but sometimes of 4 to 11 oval or oblong leaflets, marked with white crescent, often dark-spotted near centre; stipules egg-shaped, sharply pointed, strongly veined, more than ½ in. long.

Preferred Habitat—Fields, meadows, roadsides.

Flowering Season—April–November.

Distribution—Common throughout Canada and United States.

Meadows bright with clover-heads among the grasses, daisies, and buttercups in June resound with the murmur of unwearying industry and rapturous enjoyment. Bumblebees by the tens of thousands buzzing above acres of the farmer’s clover blossoms should be happy in a knowledge of their benefactions, which doubtless concern them not at all. They have never heard the story of the Australians who imported quantities of clover for fodder, and had glorious fields of it that season, but not a seed to plant next year’s crops, simply because the farmers had failed to import the bumblebee. After her immigration the clovers multiplied prodigiously.

No; the bee’s happiness rests on her knowledge that only the butterflies’ long tongues can honestly share with her the brimming wells of nectar in each tiny floret. Children who have sucked them too appreciate her rapture. If we examine a little flower under the magnifying glass, we shall see why its structure places it in the pea family. Bumblebees so depress the keel either when they sip, or feed on pollen, that their heads and tongues get well dusted with the yellow powder, which they transfer to the stigmas of other flowers; whereas the butterflies are of doubtful value, if not injurious, since their long, slender tongues easily drain the nectar without depressing the keel. Even if a few grains of pollen should cling to their tongues, it would probably be wiped off as they withdrew them through the narrow slit, where the petals nearly meet, at the mouth of the flower. Bombus terrestris delights in nipping holes at the base of the tube, which other pilferers also profit by. Our country is so much richer in butterflies than Europe, it is scarcely surprising that Professor Robertson found thirteen Lepidoptera out of twenty insect visitors to this clover in Illinois, whereas Müller caught only eight butterflies on it out of a list of thirty-nine visitors in Germany. The fritillaries and the sulphurs are always seen about the clover fields among many others, and the “dusky wings” and the caterpillar of several species feed almost exclusively on this plant.

“To live in clover,” from the insect’s point of view at least, may well mean a life of luxury and affluence. Most peasants in Europe will tell you that a dream about the flower foretells not only a happy marriage, but long life and prosperity. For ages the clover has been counted a mystic plant, and all sorts of good and bad luck were said to attend the finding of variations of its leaves which had more than the common number of leaflets. At evening these leaflets fold downward, the side ones like two hands clasped in prayer, the end one bowed over them. In this fashion the leaves of the white and other clovers also go to sleep, to protect their sensitive surfaces from cold by radiation, it is thought.

White Sweet Clover; Bokhara or Tree Clover; White Melilot; Honey Lotus
Melilotus alba

Flowers—Small, white, fragrant, papilionaceous, the standard petal a trifle longer than the wings; borne in slender racemes. Stem: 3 to 10 ft. tall, branching. Leaves: Rather distant, petioled, compounded of 3 oblong, saw-edged leaflets; fragrant, especially when dry.

Preferred Habitat—Waste lands, roadsides.

Flowering Season—June–November.

Distribution—United States, Europe, Asia.

Both the White and the Yellow Sweet Clover put their leaves to sleep at night in a remarkable manner: the three leaflets of each leaf twist through an angle of 90 degrees, until one edge of each vertical blade is uppermost. The two side leaflets, Darwin found, always tend to face the north with their upper surface, one facing north-northwest and the other north-northeast, while the terminal leaflet escapes the chilling of its sensitive upper surface through radiation by twisting to a vertical also, but bending to either east or west, until it comes in contact with the vertical upper surface of either of the side leaflets. Thus the upper surface of the terminal and of at least one of the side leaflets is sure to be well protected through the night; one is “left out in the cold.”

The dried branches of sweet clover will fill a room with delightful fragrance; but they will not drive away flies, nor protect woollens from the ravages of moths, as old women once taught us to believe.


The ubiquitous White or Dutch Clover (Trifolium repens), whose creeping branches send up solitary round heads of white or pinkish flowers on erect, leafless stems, from May to December, in fields, open waste land, and cultivated places throughout our area, Europe, and Asia, devotes itself to wooing bees, since these are the only insects that effect cross-fertilization regularly, other visitors aiding it only occasionally. Its foliage is the favorite food of very many species of caterpillars and of all grazing cattle the world around. This is still another plant frequently miscalled shamrock. Good luck or bad attends the finding of the leaves, when compounded of an even or an odd number of leaflets more than the normal count, according to the saying of many simple-minded folk.

Blue, Tufted, or Cow Vetch or Tare; Cat Peas; Tinegrass
Vicia Cracca

Flowers—Blue, later purple; ½ in. long, growing downward in 1-sided spike, 15 to 40 flowered; calyx oblique, small, with unequal teeth; corolla butterfly-shaped, consisting of standard, wings, and keel, all oblong; the first clawed, the second oblique, and adhering to the shorter keel; 10 stamens, 1 detached from other 9. Stem: Slender, weak, climbing or trailing, downy, 2 to 4 ft. long. Leaves: Tendril bearing, divided into 18 to 24 thin, narrow, oblong leaflets. Fruit: A smooth pod 1 in. long or less, 5 to 8 seeded.

Preferred Habitat—Dry soil, fields, waste land.

Flowering Season—June–August.

Distribution—United States from New Jersey, Kentucky, and Iowa northward and northwestward. Europe and Asia.

Dry fields blued with the bright blossoms of the Tufted Vetch, and roadsides and thickets where the angular vine sends forth vivid patches of color, resound with the music of happy bees. Although the parts of the flower fit closely together, they are elastic, and opening with the energetic visitor’s weight and movement give ready access to the nectary. On his departure they resume their original position, to protect both nectar and pollen from rain and pilferers whose bodies are not perfectly adapted to further the flower’s cross-fertilization. The common bumblebee (Bombus terrestris) plays a mean trick, all too frequently, when he bites a hole at the base of the blossom, not only gaining easy access to the sweets for himself, but opening the way for others less intelligent than he, but quite ready to profit by his mischief, and so defeat nature’s plan. Doctor Ogle observed that the same bee always acts in the same manner, one sucking the nectar legitimately, another always biting a hole to obtain it surreptitiously, the natural inference, of course, being that some bees, like small boys, are naturally depraved.

Ground-nut
Apios tuberosa (A. Apios)

Flowers—Fragrant, chocolate brown and reddish purple, numerous, about ½ in. long, clustered in racemes from the leaf axils. Calyx 2-lipped, corolla papilionaceous, the broad standard petal turned backward, the keel sickle-shaped; stamens within it 9 and 1. Stem: From tuberous, edible rootstock; climbing, slender, several feet long, the juice milky. Leaves: Compounded of 5 to 7 ovate leaflets. Fruit: A leathery, slightly curved pod, 2 to 4 in. long.

Preferred Habitat—Twining about undergrowth and thickets in moist or wet ground.

Flowering Season—July–September.

Distribution—New Brunswick to Ontario, south to the Gulf states and Kansas.

No one knows better than the omnivorous “barefoot boy” that

“Where the ground-nut trails its vine”

there is hidden something really good to eat under the soft, moist soil where legions of royal fern, usually standing guard above it, must be crushed before he digs up the coveted tubers. He would be the last to confuse it with the Wild Kidney Bean or Bean Vine (Phaseolus polystachyus). The latter has loose racemes of smaller purple flowers and leaflets in threes; nevertheless it is often confounded with the ground-nut vine by older naturalists whose knowledge was “learned of schools.”

Wild or Hog Peanut
Amphicarpa monoica (Falcata comosa)

Flowers—Numerous small, showy ones, borne in drooping clusters from axils of upper leaves; lilac, pale purplish, or rarely white, butterfly-shaped, consisting of standard petal partly enfolding wings and keel. Calyx tubular, 4 or 5 toothed; 10 stamens (9 and 1); 1 pistil. (Also solitary fertile flowers, lacking petals, on thread-like, creeping branches from lower axils or underground.) Stem: Twining wiry brownish-hairy, 1 to 8 ft. long. Leaves: Compounded of 3 thin leaflets, egg-shaped at base, acutely pointed at tip. Fruit: Hairy pod 1 in. long. Also 1-seeded, pale, rounded, underground peanut.

Preferred Habitat—Moist thickets, shady roadsides.

Flowering Season—August–September.

Distribution—New Brunswick westward to Nebraska, south to Gulf of Mexico.

Amphicarpa (“seed at both ends”), the Greek name by which this graceful vine is sometimes known, emphasizes its most interesting feature, that, nevertheless, seems to many a foolish duplication of energy on Nature’s part. Why should the same plant bear two kinds of blossoms and seeds? Among the foliage of low shrubbery and plants in shady lanes and woodside thickets, we see the delicate, drooping clusters of lilac blossoms hanging where bees can readily discover them and, in pilfering their sweets, transfer their pollen from flower to flower. But in case of failure to intercross these blossoms that are dependent upon insect help to set fertile seed, what then? Must the plant run the risk of extinction? Self-fertilization may be an evil, but failure to produce seed at all is surely the greatest one. To guard against such a calamity, insignificant looking flowers that have no petals to open for the enticing of insects, but which fertilize themselves with their own pollen, produce abundant seed close to the ground or under it. Then what need of the showy blossoms hanging in the thicket above? Close inbreeding in the vegetable world, as in the animal, ultimately produces degenerate offspring; and although the showy lilac blossoms of the wild peanut yield comparatively few cross-fertilized seeds, these are quite sufficient to enable the vine to maintain those desired features which are the inheritance from ancestors that struggled in their day and generation after perfection. No plant dares depend upon its cleistogamous or blind flowers alone for offspring; and in the sixty or more genera containing these curious growths, that usually look like buds arrested in development, every plant that bears them bears also showy flowers dependent upon cross-pollination by insect aid.

The boy who:

“Drives home the cows from the pasture
Up through the long shady lane”

knows how reluctantly they leave the feast afforded by the wild peanut. Hogs, rooting about in the moist soil where it grows, unearth the hairy pods that should produce next year’s vines; hence the poor excuse for branding a charming plant with a repellent folk-name.

This plant should not be confused with pig-nut (carya porcina), which is a species of hickory.

WOOD-SORREL FAMILY (Oxalidaceae)

White or True Wood-sorrel; Alleluia
Oxalis acetosella

Flowers—White or delicate pink, veined with deep pink, about ½ in. long. Five sepals; 5 spreading petals rounded at tips; 10 stamens, 5 longer, 5 shorter, all anther-bearing; 1 pistil with 5 stigmatic styles. Scape: Slender, leafless, 1-flowered, 2 to 5 in. high. Leaf: Clover-like, of 3 leaflets, on long petioles from scaly, creeping rootstock.

Preferred Habitat—Cold, damp woods.

Flowering Season—May–July.

Distribution—Nova Scotia and Manitoba, southward to North Carolina. Also a native of Europe.

Clumps of these delicate little pinkish blossoms and abundant leaves, cuddled close to the cold earth of northern forests, usually conceal near the dry leaves or moss from which they spring blind flowers that never open—cleistogamous the botanists call them—flowers that lack petals, as if they were immature buds; that lack odor, nectar, and entrance; yet they are perfectly mature, self-fertilized, and abundantly fruitful. Fifty-five genera of plants contain one or more species on which these peculiar products are found, the pea family having more than any other, although violets offer perhaps the most familiar instance to most of us. Many of these species bury their offspring below ground; but the wood-sorrel bears its blind flowers nodding from the top of a curved scape at the base of the plant, where we can readily find them. By having no petals, and other features assumed by an ordinary flower to attract insects, and chiefly in saving pollen, they produce seed with literally the closest economy. It is estimated that the average blind flower of the wood-sorrel does its work with four hundred pollen grains, while the prodigal peony scatters with the help of wind and insect visitors more than three and a half millions!

As self-fertilization is impossible, the showy blossoms of the wood-sorrel are a necessity not a luxury; for the insects must not be allowed to overlook them.

Every child knows how the wood-sorrel “goes to sleep” by drooping its three leaflets until they touch back to back at evening, regaining the horizontal at sunrise—a performance most scientists now agree protects the peculiarly sensitive leaf from cold by radiation. During the day as well, seedling, scape, and leaves go through some interesting movements, closely followed by Darwin in his “Power of Movement in Plants,” which should be read by all interested.

Oxalis, the Greek for sour, applies to all sorrels because of their acid juice; but acetosella = vinegar salt, the specific name of this plant, indicates that from it druggists obtain salt of lemons. Twenty pounds of leaves yield between two and three ounces of oxalic acid by crystallization. Names locally given the plant in the Old World are wood sour or sower, cuckoo’s meat, sour trefoil, and shamrock—for this is St. Patrick’s own flower, the true shamrock of the ancient Irish, some claim. Alleluia, another folk-name, refers to the joyousness of the Easter season, when the plant comes into bloom in England.

Violet Wood-sorrel
Oxalis violacea

Flowers—Pinkish purple, lavender, or pale magenta; less than 1 in. long; borne on slender stems in umbels or forking clusters, each containing from 3 to 12 flowers. Calyx of 5 obtuse sepals; 5 petals; 10 (5 longer, 5 shorter) stamens; 5 styles persistent above 5-celled ovary. Stem: From brownish, scaly bulb 4 to 9 in. high. Leaves: About 1 in. wide, compounded of 3 rounded, clover-like leaflets with prominent midrib borne at end of slender petioles, springing from root.

Preferred Habitat—Rocky and sandy woods.

Flowering Season—May–June.

Distribution—Northern United States to Rocky Mountains, south to Florida and New Mexico; more abundant southward.

Beauty of leaf and blossom is not the only attraction possessed by this charming little plant. As a family the wood-sorrels have great interest for botanists since Darwin devoted such exhaustive study to their power of movement, and many other scientists have described the several forms assumed by perfect flowers of the same species to secure cross-fertilization. Some members of the clan also bear blind flowers, which have been described in the account of the white wood-sorrel. Even the rudimentary leaves of the seedlings “go to sleep” at evening, and during the day are in constant movement up and down. The stems, too, are restless; and as for the mature leaves, every child knows how they droop their three leaflets back to back against the stem at evening, elevating them to the perfect horizontal again by day. Extreme sensitiveness to light has been thought to be the true explanation of so much activity, and yet this is not a satisfactory theory in many cases. It is certain that drooping leaves suffer far less from frost than those whose upper surfaces are flatly exposed to the zenith. This view that the sleep of leaves saves them from being chilled at night by radiation is Darwin’s own, supported by innumerable experiments; and probably it would have been advanced by Linnaeus, too, since so many of his observations in “Somnus Plantarum” verify the theory, had the principle of radiation been discovered in his day.

GERANIUM FAMILY (Geraniaceae)

Wild or Spotted Geranium or Crane’s-Bill; Alum-root
Geranium maculatum

Flowers—Pale magenta, purplish pink, or lavender, regular, 1 to 1½ in. broad, solitary or a pair, borne on elongated peduncles, generally with pair of leaves at their base. Calyx of 5 lapping, pointed sepals; 5 petals, woolly at base; 10 stamens; 1 pistil with 5 styles. Fruit: A slender capsule pointed like a crane’s bill. In maturity it ejects seeds elastically far from the parent plant. Stem: 1 to 2 ft. high, hairy, slender, simple or branching above. Leaves: Older ones sometimes spotted with white; basal ones 3 to 6 in. wide, 3 to 5 parted, variously cleft and toothed; 2 stem leaves opposite.

Preferred Habitat—Open woods, thickets, and shady roadsides.

Flowering Season—April–July.

Distribution—Newfoundland to Georgia, and westward a thousand miles.

Sprengel, who was the first to exalt flowers above the level of mere botanical specimens, had his attention led to the intimate relationship existing between plants and insects by studying out the meaning of the hairy corolla of the common Wild Geranium of Germany (G. sylvaticum), being convinced, as he wrote in 1787, that “the wise Author of Nature has not made even a single hair without a definite design.” A hundred years before, Nehemias Grew had said that it was necessary for pollen to reach the stigma of a flower in order that it might set fertile seed; and Linnaeus had to come to his aid with conclusive evidence to convince a doubting world that this was true. Sprengel made the next step forward, but his writings lay neglected over seventy years because he advanced the then incredible and only partially true statement that a flower is fertilized by insects which carry its pollen from its anthers to its stigma. In spite of his discoveries that the hairs inside the geranium’s corolla protect its nectar from rain for the insect’s benefit, just as eyebrows keep perspiration from falling into the eye; that most flowers which secrete nectar have what he termed “honey guides”—spots of bright color, heavy veining, or some such pathfinder on the petals—in spite of the most patient and scientific research that shed great light on natural selection a half-century before Darwin advanced the theory, he left it for the author of “The Origin of Species” to show that cross-fertilization—the transfer of pollen from one blossom to another, not from anthers to stigma of the same flower—is the great end to which so much marvellous mechanism is chiefly adapted. Cross-fertilized blossoms defeat self-fertilized flowers in the struggle for existence.

No wonder Sprengel’s theory was disproved by his scornful contemporaries in the very case of his Wild Geranium, which sheds its pollen before it has developed a stigma to receive any; therefore no insect that had not brought pollen from an earlier bloom could possibly fertilize this flower. How amazing that he did not see this! Our common wild crane’s-bill, which also has lost the power to fertilize itself, not only ripens first the outer, then the inner, row of anthers, but actually drops them off after their pollen has been removed, to overcome the barest chance of self-fertilization as the stigmas become receptive. This is the geranium’s and many other flowers’ method to compel cross-fertilization by insects. In cold, stormy, cloudy weather a geranium blossom may remain in the male stage several days before becoming female; while on a warm, sunny day, when plenty of insects are flying, the change sometimes takes place in a few hours. Among others, the common sulphur or puddle butterfly, that sits in swarms on muddy roads and makes the clover fields gay with its bright little wings, pilfers nectar from the geranium without bringing its long tongue in contact with the pollen. Neither do the smaller bees and flies which alight on the petals necessarily come in contact with the anthers and stigmas. Doubtless the larger bees are the flowers’ true benefactors.

The so-called geraniums in cultivation are pelargoniums, strictly speaking.

Herb Robert; Red Robin; Red Shanks; Dragon’s Blood
Geranium Robertianum

Flowers—Purplish rose, about ½ in. across, borne chiefly in pairs on slender peduncles. Five sepals and petals; stamens 10; pistil with 5 styles. Stem: Weak, slender, much branched, forked, and spreading, slightly hairy, 6 to 18 in. high. Leaves: Strongly scented, opposite, thin, of 3 divisions, much subdivided and cleft. Fruit: Capsular, elastic, the beak 1 in. long, awn-pointed.

Preferred Habitat—Rocky, moist woods and shady roadsides.

Flowering Season—May–October.

Distribution—Nova Scotia to Pennsylvania, and westward to Missouri.

Who was the Robert for whom this his “holy herb” was named? Many suppose that he was St. Robert, a Benedictine monk, to whom the twenty-ninth of April—the day the plant comes into flower in Europe—is dedicated. Others assert that Robert Duke of Normandy, for whom the “Ortus Sanitatis,” a standard medical guide for some hundred of years, was written, is the man honored; and since there is now no way of deciding the mooted question, we may take our choice.

Only when the stems are young are they green; later the plant well earns the name of Red Shanks, and when its leaves show crimson stains, of Dragon’s Blood.

At any time the herb gives forth a disagreeable odor, but especially when its leaves and stem have been crushed until they emit a resinous secretion once an alleged cure for the plague.

MILKWORT FAMILY (Polygalaceae)

Fringed Milkwort or Polygala; Flowering Wintergreen; Gay Wings
Polygala paucifolia

Flowers—Purplish rose, rarely white, showy, over ½ in. long, from 1 to 4 on short, slender peduncles from among upper leaves. Calyx of 5 unequal sepals, of which 2 are wing-like and highly colored like petals. Corolla irregular, its crest finely fringed; 6 stamens; 1 pistil. Also pale, pouch-like, cleistogamous flowers underground. Stem: Prostrate, 6 to 15 in. long, slender, from creeping rootstock, sending up flowering shoots 4 to 7 in. high. Leaves: Clustered at summit, oblong, or pointed egg-shaped, 1½ in. long or less; those on lower part of shoots scale-like.

Preferred Habitat—Moist, rich woods, pine lands, light soil.

Flowering Season—May–July.

Distribution—Northern Canada, southward and westward to Georgia and Illinois.

Gay companies of these charming, bright little blossoms hidden away in the woods suggest a swarm of tiny mauve butterflies that have settled among the wintergreen leaves. Unlike the common milkwort and many of its kin that grow in clover-like heads, each one of the gay wings has beauty enough to stand alone. Its oddity of structure, its lovely color and enticing fringe, lead one to suspect it of extraordinary desire to woo some insect that will carry its pollen from blossom to blossom and so enable the plant to produce cross-fertilized seed to counteract the evil tendencies resulting from the more prolific self-fertilized cleistogamous flowers buried in the ground below.

Common, Field, or Purple Milkwort; Purple Polygala
Polygala sanguinea (P. viridescens)

Flowers—Numerous, very small, variable; bright magenta pink, or almost red, or pale to whiteness, or greenish, clustered in a globular clover-like head, gradually lengthening to a cylindric spike. Stem: 6 to 15 in. high, smooth, branched above, leafy. Leaves: Alternate, narrowly oblong, entire.

Preferred Habitat—Fields and meadows, moist or sandy.

Flowering Season—June–September.

Distribution—Southern Canada to North Carolina, westward to the Mississippi.

When these bright clover-like heads and the inconspicuous greenish ones grow together, the difference between them is so striking it is no wonder Linnaeus thought they were borne by two distinct species, Sanguinea and viridescens, whereas they are now known to be merely two forms of the same flower. At first glance one might mistake the irregular little blossom for a member of the pea family; two of the five very unequal sepals—not petals—are colored wings. These bright-hued calyx-parts overlap around the flower-head like tiles on a roof. Within each pair of wings are three petals united into a tube, split on the back, to expose the vital organs to contact with the bee, the milkwort’s best friend.

Plants of this genus were named polygala, the Greek for much milk, not because they have milky juice—for it is bitter and clear—but because feeding on them is supposed to increase the flow of cattle’s milk.

TOUCH-ME-NOT FAMILY (Balsaminaceae)

TOUCH-ME-NOT OR JEWEL-WEED

Jewel-weed; Spotted Touch-me-not; Silver Cap; Wild Balsam; Lady’s Eardrops; Snap Weed; Wild Lady’s Slipper
Impatiens biflora (I. fulva)

Flowers—Orange yellow, spotted with reddish brown, irregular, 1 in. long or less, horizontal, 2 to 4 pendent by slender footstalks on a long peduncle from leaf axils. Sepals, 3, colored; 1 large, sac-shaped, contracted into a slender incurved spur and 2-toothed at apex; 2 other sepals small. Petals, 3; 2 of them 2-cleft into dissimilar lobes; 5 short stamens, 1 pistil. Stem: 2 to 5 ft. high, smooth, branched, colored, succulent. Leaves: Alternate, thin, pale beneath, ovate coarsely toothed, petioled. Fruit: An oblong capsule, its 5 valves opening elastically to expel the seeds.

Preferred Habitat—Beside streams, ponds, ditches; moist ground.

Flowering Season—July–October.

Distribution—Nova Scotia to Oregon, south to Missouri and Florida.

.

These exquisite, bright flowers, hanging at a horizontal, like jewels from a lady’s ear, may be responsible for the plant’s folk-name; but whoever is abroad early on a dewy morning, or after a shower, and finds notched edges of the drooping leaves hung with scintillating gems, dancing, sparkling in the sunshine, sees still another reason for naming this the Jewel-weed. In a brook, pond, spring, or wayside trough, which can never be far from its haunts, dip a spray of the plant to transform the leaves into glistening silver. They shed water much as the nasturtiums do.

When the tiny ruby-throated humming bird flashes northward out of the tropics to spend the summer, where can he hope to find nectar so deeply secreted that not even the long-tongued bumblebee may rob him of it all? Beyond the bird’s bill his tongue can be run out and around curves no other creature can reach. Now the early-blooming columbine, its slender cornucopias brimming with sweets, welcomes the messenger whose needle-like bill will carry pollen from flower to flower; presently the coral honeysuckle and the scarlet painted-cup attract him by wearing his favorite color; next the jewel-weed hangs horns of plenty to lure his eye; and the trumpet vine and cardinal flower continue to feed him successively in Nature’s garden; albeit cannas, nasturtiums, salvia, gladioli, and such deep, irregular showy flowers in men’s flower beds sometimes lure him away.

Familiar as we may be with the nervous little seed-pods of the touch-me-not, which children ever love to pop and see the seeds fly, as they do from balsam pods in grandmother’s garden, they still startle with the suddenness of their volley. Touch the delicate hair-trigger at the end of a capsule, and the lightning response of the flying seeds makes one jump. They sometimes land four feet away. At this rate of progress a year, and with the other odds against which all plants have to contend, how many generations must it take to fringe even one mill pond with jewel-weed; yet this is rapid transit indeed compared with many of Nature’s processes. The plant is a conspicuous sufferer from the dodder.


The Pale Touch-me-not (I. aurea)—I. pallida of Gray—most abundant northward, a larger, stouter species found in similar situations, but with paler yellow flowers only sparingly dotted if at all, has its broader sac-shaped sepal abruptly contracted into a short, notched, but not incurved spur. It shares its sister’s popular names.

BUCKTHORN FAMILY (Rhamnaceae)

New Jersey Tea; Wild Snowball; Red-root
Ceanothus americanus

Flowers—Small, white, on white pedicels, crowded in dense, oblong, terminal clusters. Calyx white, hemispheric, 5-lobed; 5 petals, hooded and long-clawed; 5 stamens with long filaments; style short, 3-cleft. Stems: Shrubby, 1 to 3 ft. high, usually several, from a deep reddish root. Leaves: Alternate, ovate-oblong, acute at tip, finely saw-edged, 3-nerved, on short petioles.

Preferred Habitat—Dry, open woods and thickets.

Flowering Season—May–July.

Distribution—Ontario south and west to the Gulf of Mexico.

Light, feathery clusters of white little flowers crowded on the twigs of this low shrub interested thrifty colonial housewives of Revolutionary days not at all; the tender, young, rusty, downy leaves were what they sought to dry as a substitute for imported tea. Doubtless the thought that they were thereby evading George the Third’s tax and brewing patriotism in every kettleful added a sweetness to the home-made beverage that sugar itself could not impart. The American troops were glad enough to use New Jersey Tea throughout the war. A nankeen or cinnamon-colored dye is made from the reddish root.

MALLOW FAMILY (Malvaceae)

Swamp Rose-mallow; Mallow Rose
Hibiscus Moscheutos

Flowers—Very large, clear rose pink, sometimes white, often with crimson centre, 4 to 7 in. across, solitary, or clustered on peduncles at summit of stems. Calyx 5-cleft, subtended by numerous narrow bractlets; 5 large, veined petals; stamens united into a valvular column bearing anthers on the outside for much of its length; 1 pistil partly enclosed in the column, and with 5 button-tipped stigmatic branches above. Stem: 4 to 7 ft. tall, stout, from perennial root. Leaves: 3 to 7 in. long, tapering, pointed, egg-shaped, densely white, downy beneath; lower leaves, or sometimes all, lobed at middle.

Preferred Habitat—Brackish marshes, riversides, lake shores, saline situations.

Flowering Season—August–September.

Distribution—Massachusetts to the Gulf of Mexico, westward to Louisiana; found locally in the interior, but chiefly along Atlantic seaboard.

Stately ranks of these magnificent flowers, growing among the tall sedges and “cat-tails” of the marshes, make the most insensate traveller exclaim at their amazing loveliness. To reach them one must don rubber boots and risk sudden seats in the slippery ooze; nevertheless, with spade in hand to give one support, it is well worth while to seek them out and dig up some roots to transplant to the garden. Here, strange to say, without salt soil or more water than the average garden receives from showers and hose, this handsomest of our wild flowers soon makes itself delightfully at home under cultivation. Such good, deep earth, well enriched and moistened, as the hollyhock thrives in, suits it perfectly. Now we have a better opportunity to note how the bees suck the five nectaries at the base of the petals, and collect the abundant pollen of the newly-opened flowers, which they perforce transfer to the five button-shaped stigmas intentionally impeding the entrance to older blossoms. Only its cousin the hollyhock, a native of China, can vie with the rose-mallow’s decorative splendor among the shrubbery; and the Rose of China (Hibiscus Rosa-Sinensis), cultivated in greenhouses here, eclipse it in the beauty of the individual blossom. This latter flower, whose superb scarlet corolla stains black, is employed by the Chinese married women, it is said, to discolor their teeth; but in the West Indies it sinks to even greater ignominy as a dauber for blacking shoes!

Marsh Mallow (Althaea officinalis), a name frequently misapplied to the Swamp Rose-mallow, is properly given to a much smaller pink flower, measuring only an inch and a half across at the most, and a far rarer one, being a naturalized immigrant from Europe found only in the salt marshes from the Massachusetts coast to New York. It is also known as Wymote. This is a bushy, leafy plant, two to four feet high, and covered with velvety down as a protection against the clogging of its pores by the moisture arising from its wet retreats. Plants that live in swamps must “perspire” freely and keep their pores open. From the Marsh Mallow’s thick roots the mucilage used in confectionery is obtained, a soothing demulcent long esteemed in medicine.

ST. JOHN’S-WORT FAMILY (Hypericaceae)

SHRUBBY ST. JOHN’S WORT

Common St. John’s-wort
Hypericum perforatum

Flowers—Bright yellow, 1 in. across or less, several or many in terminal clusters. Calyx of 5 lance-shaped sepals; 5 petals dotted with black; numerous stamens in 3 sets; 3 styles. Stem: 1 to 2 ft. high, erect, much branched. Leaves: Small, opposite, oblong, more or less black-dotted.

Preferred Habitat—Fields, waste lands, roadsides.

Flowering Season—June–September.

Distribution—Throughout our area, except the extreme North; Europe and Asia.

“Gathered upon a Friday, in the hour of Jupiter when he comes to his operation, so gathered, or borne, or hung upon the neck, it mightily helps to drive away all phantastical spirits.” These are the blossoms which have been hung in the windows of European peasants for ages on St. John’s eve, to avert the evil eye and the spells of the spirits of darkness. “Devil chaser” its Italian name signifies. To cure demoniacs, to ward off destruction by lightning, to reveal the presence of witches, and to expose their nefarious practices, are some of the virtues ascribed to this plant, which superstitious farmers have spared from the scythe and encouraged to grow near their houses until it has become, even in this land of liberty, a troublesome weed at times. “The flower gets its name,” says F. Schuyler Mathews, “from the superstition that on St. John’s day, the 24th of June, the dew which fell on the plant the evening before was efficacious in preserving the eyes from disease. So the plant was collected, dipped in oil, and thus transformed into a balm for every wound.” Here it is a naturalized immigrant, not a native. A blooming plant, usually with many sterile shoots about its base, has an unkempt, untidy look; the seed capsules and the brown petals of withered flowers remaining among the bright yellow buds through a long season.

The Shrubby St. John’s-wort (H. prolificum) bears yellow blossoms, about half an inch across, which are provided with stamens so numerous, the many flowered terminal clusters have a soft, feathery effect. In the axils of the oblong, opposite leaves are tufts of smaller ones, the stout stems being often concealed under a wealth of foliage. Sandy or rocky places from New Jersey southward best suit this low, dense, diffusely branched shrub which blooms prolifically from July to September.

Farther north, and westward to Iowa, the Great or Giant St. John’s-wort (H. Ascyron) brightens the banks of streams at midsummer with large blossoms, each on a long footstalk in a few-flowered cluster.

ROCKROSE FAMILY (Cistaceae)

Long-branched Frost-weed; Frost-flower; Frost-wort; Canadian Rockrose
Helianthemum canadense

Flowers—Solitary, or rarely 2; about 1 in. across, 5-parted, with showy yellow petals; the 5 unequal sepals hairy. Also abundant small flowers lacking petals, produced from the axils later. Stem: Erect, 3 in. to 2 ft. high; at first simple, later with elongated branches. Leaves: Alternate, oblong, almost seated on stem.

Preferred Habitat—Dry fields, sandy or rocky soil.

Flowering Season—Petal-bearing flowers, May–July.

Distribution—New England to the Carolinas, westward to Wisconsin and Kentucky.

When the stubble in the dry fields is white some cold November morning, comparatively few notice the ice crystals, like specks of glistening quartz, at the base of the stems of this plant. The similar Hoary Frost-weed (H. majus), whose showy flowers appear in clusters at the hoary stem’s summit in June and July, also bears them. Often this ice formation assumes exquisite feathery, whimsical forms, bursting the bark asunder where an astonishing quantity of sap gushes forth and freezes. Indeed, so much sap sometimes goes to the making of this crystal flower, that it would seem as if an extra reservoir in the soil must pump some up to supply it with its large fantastic corolla.

VIOLET FAMILY (Violaceae)

COMMON PURPLE VIOLET

Blue and Purple Violets

Lacking perfume only to be a perfectly satisfying flower, the Common Purple, Meadow, or Hooded Blue Violet (V. cucullata) has nevertheless established itself in the hearts of the people from the Arctic to the Gulf as no sweet-scented, showy, hothouse exotic has ever done. Royal in color as in lavish profusion, it blossoms everywhere—in woods, waysides, meadows, and marshes, but always in finer form in cool, shady dells; with longer flowering scapes in meadow bogs; and with longer leaves than wide in swampy woodlands. The heart-shaped, saw-edged leaves, folded toward the centre when newly put forth, and the five-petalled, bluish-purple, golden-hearted blossom are too familiar for more detailed description. From the three-cornered stars of the elastic capsules, the seeds are scattered abroad.

In shale and sandy soil, even in the gravel of hillsides, one finds the narrowly divided, finely cut leaves and the bicolored beardless blossom of the Bird’s-foot Violet (V. pedata), pale bluish purple on the lower petals, dark purple on one or two upper ones, and with a heart of gold. The large, velvety, pansy-like blossom and the unusual foliage which rises in rather dense tufts are sufficient to distinguish the plant from its numerous kin. This species produces no cleistogamous or blind flowers. Frequently the Bird’s-foot Violet blooms a second time, in autumn, a delightful eccentricity of this family. The spur of its lower petal is long and very slender, and, as might be expected, the longest-tongued bees and butterflies are its most frequent visitors. These receive the pollen on the base of the proboscis.

In course of time the lovely English, March, or Sweet Violet (V. odorata), which has escaped from gardens, and which is now rapidly increasing with the help of seed and runners on the Atlantic and the Pacific coasts, may be established among our wild flowers. No blossom figures so prominently in European literature. In France, it has even entered the political field since Napoleon’s day. Yale University has adopted the violet for its own especial flower, although it is the corn-flower, or bachelor’s button (Centaurea cyanus) that is the true Yale blue. Sprengel, who made a most elaborate study of the violet, condensed the result of his research into the following questions and answers, which are given here because much that he says applies to our own native species, which have been too little studied in the modern scientific spirit:

“1. Why is the flower situated on a long stalk which is upright, but curved downward at the free end? In order that it may hang down; which, firstly, prevents rain from obtaining access to the nectar; and, secondly, places the stamens in such a position that the pollen falls into the open space between the pistil and the free ends of the stamens. If the flower were upright, the pollen would fall into the space between the base of the stamen and the base of the pistil, and would not come in contact with the bee.

“2. Why does the pollen differ from that of most other insect-fertilized flowers? In most of such flowers the insects themselves remove the pollen from the anthers, and it is therefore important that the pollen should not easily be detached and carried away by the wind. In the present case, on the contrary, it is desirable that it should be looser and drier, so that it may easily fall into the space between the stamens and the pistil. If it remained attached to the anther, it would not be touched by the bee, and the flower would remain unfertilized.

“3. Why is the base of the style so thin? In order that the bee may be more easily able to bend the style.

“4. Why is the base of the style bent? For the same reason. The result of the curvature is that the pistil is much more easily bent than would be the case if the style were straight.

“5. Finally, why does the membranous termination of the upper filament overlap the corresponding portions of the two middle stamens? Because this enables the bee to move the pistil and thereby to set free the pollen more easily than would be the case under the reverse arrangement.”
