We have very little information on this species and do not know if it will be hardy in Britain. The notes below are based on the needs of other members of this genus.
Requires a loose lean gritty well-drained soil in a very sunny position[
]. Succeeds in dry soils. Tolerates exposed positions[
]. Requires some protection from winter wet[
Established plants resent root disturbance[
]. No further details are given.
An infusion of the root has been used to treat stomach disorders[
Seed - best sown as soon as it is ripe in the autumn in a sandy compost in a greenhouse. Sow stored seed in early spring in a warm greenhouse[
]. As soon as 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 out in late spring or early summer, after the last expected frosts.
Division in early spring[
]. This has to be done with care because the plant resents root disturbance[
]. Try to obtain divisions from around the edges of the plants without digging up the whole clump. Tease the divisions out with as much root on them as possible and pot them up. Grow them on in light shade in the greenhouse until they are rooting well and plant them out in the summer.
