Blueblossom is an evergreen, native to the California coastal areas, with bright green to dark green leaves and small flowers that are produced in a dense, puff-shaped clusters. Flower color varies from white, light blue, dark blue to purple. Flowers bloom in the winter or spring, and then mature into a dry, three-lobed seed capsule.
