How it is grown
Prefers a woodland soil but thrives in a warm open well-drained loam if leafmould is added. A calcifuge plant, preferring a pH between 5 and 7. Prefers the partial shade of a light woodland. Prefers a wet summer and a cool but not very frosty dry winter. Plants are not very self-compatible, self-fertilized flowers produce few seeds and these are of low viability.
Propagating it: Seed - can be sown as soon as it is ripe in a greenhouse. Stored seed should be pre-soaked for 24 hours in warm water and the hard covering around the micropyle should be filed down to leave a thin covering. It usually germinates in 1 - 3 months at 23°c. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in the greenhouse for at least their first winter. Plant them out into their permanent positions when they are more than 15cm tall and give them some protection from winter cold for their first year or three outdoors. Cuttings of almost ripe wood, 10 - 15cm with a heel, August/September in a shaded frame. High percentage but slow. Cuttings of firm wood, 7 - 10cm with a heel, end of June in a frame. Keep in a cool greenhouse for the first year. Leaf-bud cuttings, July/August in a frame.
