Sow into pots in greenhouse or indoors in later winter. Plant out to permanent spots in late spring or early summer - after threat of last frost has passed.
Divide in spring just before active growth. Plant divisions directly into their permanent spots.
Take cuttings of mature wood from the current season’s growth, 5-10cm long in early autumn. Root out with frost protection.
