Propagation
Seed - we have no information on this species but suggest sowing the seed in a cold frame in the spring. Only just cover the seed. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the cold frame for their first winter. Plant them out into their permanent positions in the spring. Division in the spring might be possible.
