Gorgeously scented pure white flowers are held above rosettes of dark green leaves. This is a biennial or short-lived perennial that readily self-seeds, often coming true to type, so it is perfect for naturising in a wildlife garden. Like all sweet rockets it is highly attractive to bees and other beneficial insects, and the fragrant flowers perfume the air in spring and early summer evenings. They are also edible and look great sprinkled over salads. Although relatively short-lived, it self-seeds freely.
