Cultivation Details
Succeeds in ordinary garden soil in a sunny position[1]. Requires a well-drained deep gritty or gravelly soil, preferably of low fertility[2]. Xanthisma spinulosum is an exceedingly complex, variable taxon. Over many parts of its range, this species is represented by a series of morphologically distinct populations in isolated mountain ranges now connected by roads. The relatively mesic road right-of-ways form corridors for migration, thus leading to gene exchange. Likewise, long distance dispersal has helped to 'blend' many of these previously isolated and distinctive forms[3].
Propagation
Seed - sow spring in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse 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.
