Deciduous shrubs which resemble Cytisus; they are reasonably hardy, although they occasionally suffer some frost damage.
Very beautiful when grown over low walls or over the edge of a sunken seating area, they look well in combination with other plants, eg irises.
Lime-free, humus-rich, but porous soil. They are very difficult to transplant.
Sow in spring; garden forms are grafted on stock.
