How it is grown
An easily grown plant, succeeding in a moist loamy soil. Most species in this genus seem to be immune to the predations of rabbits.
Propagating it: Seed - sow autumn in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division in spring or autumn. 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.
