Seed - we have no information on this species but suggest sowing the seed in a greenhouse in early spring. Prick out the seedlings into individual pots as soon as they are large enough to handle and grow them on in the greenhouse for at least their first winter. Plant them out in early summer. Cuttings in a frame in the summer. Shade them for the first 10 - 12 days[1].
Cultivation

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 should succeed outdoors in most parts of this country. The following notes are based on the general needs of the genus. Requires a well-drained soil in full sun[1][3]. Prefers a deep rather rich sandy loam[1]. Best grown in a crevice in a rock garden or on a wall[1][3]. Tolerates hot dry conditions and also drought once it is established, but disliking winter wet[4]. Plants also dislike wet summers[5].
