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 many parts of this country. The following notes are based on the general needs of the genus. Thrives in most soils and in the light shade of trees. Grows well in heavy clay soils. Prefers a moist soil in sun or semi-shade. Prefers a calcareous soil. Grows well in open woodlands. Members of this genus seem to be immune to the predations of rabbits and deer. A greedy plant, inhibiting the growth of nearby species, especially legumes.
Seed – best sown as soon as it is ripe in a cold frame. The seed can be stratified and sown in spring but will then be slow to germinate. When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for their first winter. Plant them out in late spring or early summer. Division – best done in spring but it can also be done in autumn. Another report says that division is best carried out in the autumn or late winter because the plants come into growth very early in the year.
