Plant Propagation

Seed - we have no information on this species but suggest sowing the seed in a cold frame as soon as it is ripe if this is possible, otherwise sow it in early spring. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
