Succeeds in ordinary garden soil[]. Prefers a well-drained fertile soil in full sun[].

Propagation

Seed - surface sow in a greenhouse or cold frame in the spring. If the seed does not germinate within 4 weeks it can be chilled for 3 weeks at about 3°c and then be returned to the greenhouse[]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions in the summer.
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 summer or following spring.
