Crambe cordifolia

greater sea kale

Product Image
Billowing clouds of tiny, white flowers float above huge rosettes of deeply cut dark green leaves in June and July. A favourite plant of Edwardian garden designer Gertrude Jekyll, this perennial looks magnificent at the back of a sunny border or as part of a cottage garden scheme. The tiny flowers, attractive to bees, are a perfect foil for large-flowered plants. The leaves smell strongly of cabbage and the plant needs space to spread out.

How to care for Crambe cordifolia:

Cut back the plant to ground level in autumn and apply a generous 5-7cm (2-3in) mulch of well-rotted manure or garden compost around the plant in spring.
