Cultivation details
Requires a moist humus-rich soil in semi-shade[200]. Grows well in an open woodland garden[200]. The leaves are shaped in such a way that they collect rainwater in a cavity[212]. Slugs are particularly fond of this plant and will soon destroy it if given a chance[K].

Plant Propagation
Seed - best sown as soon as it is ripe in a cold frame. The seed usually germinates in early spring. Sow stored seed as early in the year as possible. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring or autumn[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 spring.
