Seed - sow late winter in a greenhouse[1]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in late spring. Alternatively, the seed can be sown in early summer in a greenhouse, the seedlings overwintered in the greenhouse and then planted out in the following spring[1]. Division in autumn[111]. Cuttings can be taken throughout the growing season, though August/September is best[1].
