Propagation
Seed - we have no information on this species but suggest sowing the seed in a greenhouse or cold frame in early spring. Use a very freely-draining compost, prick out the seedlings into individual pots as soon as they are large enough to handle and plant out into their permanent positions when they are large enough. Careful division of the crown as the plants come into growth in spring[3].
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 at least in the milder parts of the country. This species might be no more than a synonym for W. angustifolia[5]. The following notes are based on the general needs of the genus. Requires a free-draining, gritty but moisture-retentive soil in a sunny position[3]. Plants are intolerant of drought[3].
