Sowing Months Flowering Months

Protect plants with a layer of bracken over the winter months.

Germinate on the surface of good free draining, soil-based compost. Cover with a very fine sprinkling of compost or vermiculite. Keep in a cool position at a temperature of between 15-20C (59-68F). Germination can take 1-3 months.

Transplant when large enough to handle into 7.5cm (3in) pots, and grow on overwinter in a cool, well-lit position such as a coldframe.

Plant out the following spring, 90cm (3ft) apart in moist, but well drained soil in full sun.
