Division in spring or after flowering in late summer or autumn. Division is very quick and easy, succeeding at almost any time of the year. 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.
