Plant details

Holder of the Royal Horticultural Society' prestigious Award of Garden Merit (AGM), this choice alpine is worth the extra care and attention it needs. The pale violet, bottle-shaped flowers appear in late summer in clusters of 10-20. Plants are found growing wild in rock crevices in the Alps. They will not stand winter wet so are best grown in an alpine house. Grow in gritty, sharply drained, preferably alkaline soil. If growing in pots, create a mixture of equal parts of loam, leaf mould and grit. Plant in full sun but give protection from harsh midday sun. To propagate sow seed in containers in an open frame in the autumn. Protect plants from slugs and snails.
