Seed - we have no information for this species, but suggest sowing the seed in a greenhouse in the spring, only just covering the seed and ensuring it does not dry out. Prick out the seedlings into pots once they are large enough to handle and grow them on in the greenhouse for their first year, planting them out into their permanent positions in late spring.
