DELPHINIUM Grandiflorum.
Great flowered Larkspur.
Class and Order.—Polyandria Trigynia.
Syn. Delphinium Grandiflorum. Curt. Bot. Mag. pl. 1686.
Root fibrous,—stem erect, much branched,—radical leaves on long naked petioles, multipartite, segments narrow acute,—cauline leaves sessile, verticillate, linear acute, on the lateral branches, generally single,—lower flowers on very long peduncles—calyx none—corolla very brilliant blue—outer petals five, ovate, undulate, upper one terminated by a long rugose spur—nectaries two, divided into four segments, the two lower ones marked with a bright bearded yellow spot, enclosing the parts of fructification—stamens numerous—styles three—capsules three celled.
The genus Delphinium is a beautiful and showy one, and contains almost innumerable varieties, none, however, can exceed in beauty of colour the species figured, which is a native of Siberia, and was introduced into this country about the year 1741. It is a hardy plant, of the easiest culture, not requiring any particular treatment, though it grows best in a rich brown loam—if allowed to sow its seed, a number of young plants will soon appear, which will flower the next year; this mode, however, of propagating it, is by no means certain, and therefore, in order to obtain it true, it is better to divide the roots, which may be done in spring; numerous and very beautiful varieties are constantly raised from seed. Amongst the most desirable distinct species are
| D. Aconiti. | pallidum. |
| — cheilanthum. | pictum. |
| — macranthon. | Menziesii. |
| — alpinum. | montanum. |
| — azureum. | ucranicum. |
