Thin upright stems, large flowers of ruby, tinged in apple green. True from seed and wonderful in the damp border.
Sow from February to July just covering the seed with compost. Use good moist peat or coir based seed compost. Seal inside a polythene bag, keep at 13-18C (55-60F) for 1 week, then place in a refrigerator, at 3-5C (35-41 F). Inspect regularly while in the fridge and remove immediately if they start to germinate. After 6 weeks return to warmth. Germination usually takes 30-80 days overall (at all temperatures), but if germination does not occur in 6-10 weeks return to fridge for a further 3-6 weeks.
Transplant when large enough to handle into 7.5cm (3in) pots. Acclimatise young plants to outdoor conditions before planting out 30cm (12in) apart in, moist, well drained soil, sun or part shade.
