Delphinium genus. This genus has 250 or so species of perennials and annuals. They range from attractive self-seeding annuals to dwarf alpine plants that can exceed 2.4m in height.

The tufts will elongate into upright, usually branched flowering stems which bear stalked 5-petalled flowers each with a backward-pointing nectar spur.

Grown for their spikes of irregularly cup-shaped, sometimes hooded, spurred flowers.
They are fully to half hardy and will need an open, sunny position with fertile or rich, well drained soil. In spring remove thin growths from well established plants, leaving 5-7 strong shoots. If flower spikes are removed after they fade, a second flush may be produced in late summer provided plants are fed and watered well.
Propagate D.elatum hybrids by basal cuttings only.
Discomfort if ingested. Plant may also irritate the skin. Susceptible to slugs, snails and powdery mildew.
