Towers of dense, blue purple flowers reaching up to 4 ft high make this one of our most striking native larkspur. The robust stalks rise above elegantly cut leaves featuring an appealing matte finish. The new leaves emerge in winter after a summer/fall dormancy, followed by the stunning floral display in early spring. Native to the northwest corner of our state, where it grows in oak woodlands, bright, coniferous forests and coast chaparral. Enjoys moisture in the winter and spring, but should be allowed to go somewhat dry in the summer when dormant. Provide light shade away from the coast. Attractive to butterflies and hummingbirds. All parts are poisonous if ingested.
