Growth—

Species in this genus generally require a sunny position in a well-drained soil[1, 2]. Prefers a deep rather rich sandy loam[1]. Tolerates hot dry conditions and also drought once it is established, but dislikes moist climates at any time of the year[3, 4]. Species in this genus tend to grow well in crevices in a rock garden or on a wall[1, 2].

Propagation

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.
