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 and should be sown as early in the year as possible in a cold frame or outdoor seedbed. Germination is usually good, at least 80% by late spring. 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. Cuttings of mature wood of the current year's growth, autumn in a frame. Layering in early spring.

Cultivation

We have very little information on this species and do not know if it will be hardy in Britain. The following notes are based on the general needs of the genus. Succeeds in any reasonably good soil[2]. Often bears the aecidospore stage of 'crown rust' of oats[1][3]. The species in this genus are notably resistant to honey fungus[5].
