Cultivation
An easily grown plant, succeeding in a moist loamy soil. Grows well in heavy clay soils. Succeeds in sun or semi-shade. Hardy to about -25°c. Most species in this genus seem to be immune to the predations of rabbits. Succeeds in a woodland or semi-wild garden, it often spreads wildly.
Propagation
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.
