Delphinium

Delphinium is a genus of about 300 species of perennial flowering plants in the buttercup family Ranunculaceae, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The common name, Larkspur, is shared with the closely related genus Consolida.
The leaves are deeply lobed with 3-7 toothed, pointed lobes in a palmate shape. The main flowering stem is erect, and varies greatly in size between the species, from 10 centimeters in some alpine species, up to 2 meters tall in the larger meadowland species; it is topped with a raceme of many flowers, varying in color from purple and blue to red, yellow or white. The flower has five petal-like sepals which grow together to form a hollow pocket with a spur at the end, which gives the plant its name. Within the sepals are four true petals. The seeds are small and often shiny black. The plants flower from late spring to late summer, and are pollinated by butterflies and bumble bees. Most species are toxic. Despite the toxicity, Delphinium species are used as food plants by the larvae of some Lepidoptera species including Dot Moth and Small Angle Shades.
