Rocky places, fields and sunny slopes[
We have very little information on this species, it probably requires a well drained light fertile soil in a sunny position.
One report says that it is not hardy in Britain requiring greenhouse or half-hardy treatment[
]. We have grown it in the past in Cornwall, it survived 3 winters in a cold greenhouse with us before succumbing to slugs.
The root is diuretic, emetic and purgative[
]. It is used in the treatment of rheumatism, bronchitis and feminine sterility[
]. The plant has been considered specific in treating pain, though caution is advised since it is poisonous to some mammals[
]. The plant is also strongly rubefacient, producing blisters and intense itching[
A resin is extracted with alcohol from the bark of the root[
The plant should be used with caution since it can be poisonous. See notes above on toxicity.
Yields a resin that is used in plasters[
]. No further details are given.
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 their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
