Common Name: Colewort, giant or flowering sea kale, heartleaf crambe.
Crambe cordifolia is a very large, cabbage-leaved perennial, with a tall spray of white blooms in early summer which dry and remain with the plant throughout the summer. 'Cordifolia' means 'heart-shaped.' Crambe is a genus of about 20 species in the cabbage family (Brassicaceae) and comes from the Greek word for a kind of cabbage. It is found in the Bentall Garden. Its cousin, C. maritima, sea kale, looks similar and is found in the Perennial Garden. The flowers are full of nectar and pollen, so it is an ideal plant for pollinators.
