Cultivation details

Requires a fertile well-drained soil in full sun or part-day shade[200]. Plants flower in their first year from seed and, although they are not very hardy in Britain, they can either be grown as half-hardy annuals or the tubers can be harvested in the autumn and stored overwinter in a cool frost-free place in much the same manner as dahlias[200]. Members of this genus are rarely if ever troubled by browsing deer[233].
