Crambe cordifolia, the greater sea-kale, colewort or heartleaf crambe (syn. Crambe glabrata DC.), is a species of flowering plant in the family Brassicaceae, native to the Caucasus. It has gained the Royal Horticultural Society's Award of Garden Merit.[1]
The Latin specific epithet cordifolia, meaning "heart-shaped", refers to the leaves.[2]
Growing to 2.50NaN0 tall by 1.50NaN0 broad, it is a substantial clump-forming herbaceous perennial with kidney-shaped dark green leaves, 35cm (14inches) or more in length, which die down in mid- to late summer.[3] It is cultivated in gardens for its broad crinkled foliage and spectacular multi-branched inflorescences of many small fragrant white, cruciform (cross-shaped) flowers, reaching up to 2m (07feet) high and appearing in early summer. Under droughty conditions the foliage depreciates. The plant is tap-rooted and resents disturbance.
