Description

Geyer's Larkspur is a perennial 30-60 cm tall arising from deep, branched, fibrous roots. Leaves are basal and cauline, with dense, minute pubsecence, and palmately divided with more rounded, wider lobes on basal leaves than stem leaves. Sepals are bright blue and flared, with spurs that are straight to slighty down-curved. Upper petals are whitish with blue tips, lacking prominent blue-purple lines.

Diagnostic Characteristics

Distinguished from DELPHINIUM BICOLOR by the presence of dense, minute pubscence; also distinguished from D. BICOLOR SSP. CALCICOLA by the cleft in the low petal 2 mm or less.
