Seed is very small but can be extracted from fully ripened, dry flower heads. Its viability declines within 3 months, so fresh seed has to be used for sowing. Seed is to be sown in properly drained seedbeds. Seedlings emerge in about 3 weeks[
Cuttings of semi-ripe wood, preferably with some bottom heat to encourage rooting[
