Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings. Division.
Requires a warm sunny position in a moderately fertile well-drained soil[1, 200]. Dislikes acid soils[1]. After producing large, conspicuous flowers in the spring, the plant produces lots of small very fertile cleistogamous flowers[274].
