Propagation

This section contains historical Plants For A Future notes marked noncommercial.

Seed - best sown as soon as it is ripe in a cold frame or in an outdoors seedbed if there is sufficient seed[11][2]. The seed must be separated from the fruit flesh since this contains germination inhibitors[11][3]. Stored seed should be cold stratified for 3 - 4 months and sown as early as possible in the year[3]. Scarification may also help as may a period of warm stratification before the cold stratification[11][3]. Germination, especially of stored seed, can be very slow, taking 18 months or more[3]. Prick out the seedlings of cold-frame sown seeds into individual pots as soon as they are large enough to handle and grow the plants on for their first winter in a greenhouse, planting out in the spring after the last expected frosts. Cuttings of half-ripe side shoots, July/August in a frame. Cuttings of mature wood of the current year's growth, taken with a heel if possible, autumn in a cold frame. High percentage[10]. Layering of new growth in June/July. Takes 9 months[10].

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

An easily grown plant, it succeeds in any soil of good or moderate fertility[1], ranging from acid to shallow chalk[6]. Grows well in heavy clay soils. Succeeds in poorly drained soils[6]. Succeeds in full sun or light shade[[5]. A very ornamental[1] and free-flowering plant[4]. Plants in this genus are notably resistant to honey fungus[6].
