(Geyer's Larkspur)
Family: Helleboraceae (Hellebore)
            Ranunculaceae (Buttercup)
Delphinium geyeri grows along the northern Front Range and slightly eastward onto the plains. Dense clusters of stems give the plant a bushy appearance in its vegetative stage. Leaves are deeply dissected.

Compare to Delphinium nuttallianum, which grows in similar habitats. D. nuttallianum begins flowering slightly earlier in the season. D. nuttallianum plants are less dense, appearing spindly with few stems and fewer leaves. Flowers of D. nuttallianum are often a deep blue-purple compared to the purer blue of D. geyeri. Racemes of D. geyeri tend to be longer with more flowers.
