A deciduous shrub growing to 3m by 2m at a medium rate.

It is in flower in September, and the seeds ripen in Octoberpf. The flowers are hermaphrodite (have both male and female organs) and are pollinated by insectspf.

Cultivation

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soilpf. The plant prefers acid, neutral and basic (alkaline) soilspf. It can grow in semi-shade (light woodland) or no shade. It requires moist soilpf.

Prefers a well-drained humus rich fertile soil in a sheltered position in full sunRH. Succeeds in any soil of good or moderate quality11. Dislikes shade or badly drained soils11. Plants grow best with their roots in cool moist soil and their tops in a hot sunny position. This species is hardy to about -20°cRH but plants only really succeed in the warmer counties of Britain because of their late flowering habit184. When planted in colder areas of the country, they will need protection for the first few wintersRH. The flowers only open in sunny weather219. Plants rarely require pruning219, though they respond well to pruning and trimming and this is best carried out in the spring or just after flowering219. Plants are late coming into leaf, usually around the end of May or early June182. A very ornamental plant1, there are many named varieties182.

Propagation

Seed - sow early spring in a greenhouse. Germination is usually fairly quick. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first year. Plant them out into their permanent positions in late spring or early summer. Some reports say that the seed can be sown in situ outside and that it gives a good rate of germinationTemplate:Pfaf78, 80, 113. Cuttings of half-ripe wood, July/August in a frame. Good percentage113. Cuttings of mature wood, early autumn in a frame. Good percentage113. Layering in mid summer to early autumn1.
