Cultivation details

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in most parts of this country. It is likely to tolerate maritime exposure[K]. The following notes are based on the general needs of the genus. Easily grown in a damp to wet soil in full sun or shade[162, 200]. Members of this genus are rarely if ever troubled by browsing deer[233].

Plant Propagation

Seed - sow in situ in the spring in a moist soil in light shade. If seed is in short supply it can be sown in a cold frame and be planted out in the summer. The seed usually germinates in 2 - 6 weeks at 15°c[138]. Division in spring[200]. Very easy, 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.
