Delphinium nuttallianum
Also called Nuttall's Larkspur, Sonne's Larkspur, Low Larkspur, Meadow Larkspur, Two Lobe Larkspur, Two Lobed Larkspur, Upland Larkspur
Twolobe larkspur is a low perennial wildflower of western North American meadows and sagebrush steppe, grown for its blue to purple spurred flowers. It is best given cool, well-drained conditions and full sun, since it is native to dry, open uplands.
Delphinium nuttallianum is a species of larkspur known by the common names two-lobe larkspur, upland larkspur, common larkspur, and Nuttall's larkspur (the latter name is shared with Delphinium nuttallii). It is widely distributed across western North America from California to Alberta, including mountain meadows and the majority of the sagebrush steppe, except very dry areas.
The roots vary from thin to thick. The plant has a white to pink erect stem usually not exceeding half a meter in height, which may branch several times. Deeply lobed leaves are located mostly about the base of the plant. The inflorescence occupying the top end of the stem has a few widely spaced flowers on long pedicels. The sepals are long and curl backwards or fold upon themselves. They may be purple to blue or almost white. The lower petals are the same color, while the upper are often white.
