Crambe cordifolia

Flowering Sea Kale is a broccoli relative that makes a magnificent statement in the perennial border. Huge crinkled, rounded leaves are topped by hundreds of tiny white, sweetly fragrant flowers which last about 3 weeks between June and July. These are extremely large plants with very long tap roots; they do not like to be moved so please plant accordingly.
