Masses of brilliant yellow, slightly fragrant pea-like flowers appear in long racemes on the current year's growth in summer and early autumn.[5]

The more compact cultivar 'Cyni', to 1 m (3.3 ft), has gained the Royal Horticultural Society's Award of Garden Merit. [6][7] It is hardy but prefers a sheltered position in full sun, with poor soil. It is preferable to remove the mature seed pods in autumn.[5]
