Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring.

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

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 could succeed outdoors at least in the milder parts of this country. It probably does not have any special cultivation requirements and will probably succeed in most soils in a sunny position[K].
