Western Larkspur (Delphinium occidentale)


Western Larkspur; Timpanogos, 7/24/2013, David Kenison

Also known as Showy Larkspur. From the Buttercup (Ranunculaceae) family. The genus name, Delphinium, is from the Greek word for "dolphin" and refers to the curved shape of the flower buds.

The vibrant blue and purple colors of the Larkspur make it a real standout in mountain meadows. The tall spike (often 3-6 feet) is often densely surrounded by the flowers that are from a half inch to over an inch each.

The plant is poisonous to livestock. Crushed larkspur was used by Native Americans to control lice and other insects.

A related species, the Glaucous Larkspur, has less densely-packed flowers on the stem
