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.
