Propagation

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

Seed - best sown in the autumn in a cold frame. Stored seed will require 1 - 2 months cold stratification at about 5° and should be sown as early in the year as possible in a cold frame or outdoor seedbed[3]. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on in the greenhouse or 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 frame[2]. Cuttings of mature wood of the current year's growth, autumn in a frame. Layering in early spring[4].

Cultivation

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

We have very little information on this species but it is growing well at the Hillier Arboretum in Hampshire and seems very healthy. The following notes are based on the general needs of the genus. Succeeds in any reasonably good soil[1]. The species in this genus are notably resistant to honey fungus[3].
