In heavy adobe soil near highway; soil now dry but earlier very springy. Plants associated with Camassia, Wyethia, and Poa pratensis. Roots small, fleshy, fascicled, not at all fibrous, close to the ground surface, firmly attached to the (usually) single or 2 or 3 stems; leaves strongly dimorphic, not fleshy, all plants examined (of the several hundred in the colony) eglandular; sepals deep bluish-purple, a few more nearly blue, others nearly purple, nor widely spread, but rather (expecially the lower) cupped forward; petals colored about as the the sepals, the upper ones whitish-based, the lower ones deeply bifid; follicles scarcely at all spreading; racemes spike-like, the pedicels nearly erect both in flower and fruit; here there is no indication whatever of intermediacy toward Delphinium multiplex, with which Delphinium burkei hybridizes when the two contact. Phenology: Flowers & Fruits.
