Propagation
Seed – sow spring to early summer in a greenhouse and only just cover the seed. It usually germinates in 10 – 18 days at 15°c but if it does not germinate within 4 weeks then try chilling the seed for 3 weeks in the salad compartment of a fridge[164]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. This is a hybrid species and so will not breed true from seed. Division in spring. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
