Cultivation details

We have very little information on this species and do not know if it will be hardy outdoors in Britain, though judging by its native range it should succeed outdoors in most areas of the country. A low-growing plant, spreading by means of stolons produced in the leaf axils to produce a carpet of growth[266]. It is perhaps no more than an extreme form of C. alternifolium. The following notes are based on the general needs of the genus[K]. Succeeds in most soils if they are moist. Requires a constantly wet but well-drained soil[200]. Prefers acid soils[200]. Prefers a shady position, succeeding in woodland.

Propagation

Seed - sow spring or autumn in a lightly shaded position in a cold frame. Stand the pot in 2cm of water. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a tray of water in the cold frame for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring. 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 light shade in a cold frame until they are rooting well. Plant them out in the summer or following spring.

Excellent and very comprehensive, though it contains a number of silly mistakes. Readable yet also very detailed.
