Vigorous, twining climber with pinnate leaves of up to 19 leaflets. Long pendant racemes of pea-like, fragrant flowers, which may be blue to violet, pink or white. The flowers are later followed by bean-like, velvety green seed pods.
Stems twine in a clockwise direction.
Plants may not flower until fully established, which can take five years. May be damaged by late spring frosts, best grown on a west facing wall in cold areas.
Prune twice yearly: in August, cutting new growth back to five buds, and in February, cutting shoots back to two buds. An alternative regime is to prune just once, at the end of August or early September, cutting back to two buds.
