Now available: PLANTS FOR YOUR FOOD FOREST: an important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cultivation details

Tolerates most soils[200], but prefers a good loamy soil, abundant moisture and full sunlight[11, 200]. Hybridizes freely with other members of this genus[11]. Succeeds in most soils, but requires a warm sheltered position if the wood is to ripen sufficiently to induce free flowering[184]. Hardy to about -20°c[184]. Plants flower on the previous summers growth and should be pruned immediately after flowering in order to promote new growth[182]. Special Features:Not North American native, Fragrant flowers, Blooms are very showy.

Propagation

Seed - we have no information for this species but suggest sowing the seed as soon as it is ripe in a cold frame if possible. It is likely to require stratification before it germinates, so stored seed should be sown in a cold frame as early in the year as you receive it. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on in a cold frame for their first winter. Plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood, July/August in a light sandy soil a frame. Cuttings of mature wood of the current seasons growth, 15cm long, October/November in an outdoor frame[200]. Another report says that September is a good time to do this[11]. Division of suckers in early spring[200]. They can be planted out straight into their permanent positions.
