Sow directly where they are to flower at any time of year, or sow indoors, then overwinter seedlings in the greenhouse and plant out the following spring.
To sow directly plant seeds 20mm deep, winter cold will naturally stratify the seeds with seedlings emerging the following spring.
To sow indoors surface sow onto moist well-drained seed compost, just cover with soil. Ideal temp. 18-22°C for 2-4 weeks. Then cold stratify -4°C-+4°C for 4-6 weeks then return to warmth 5-12°C where the seeds should germinate.
Germination can be slow and erratic taking 18 days-12 months. Repeat warm/ cold cycle if germination does not occur. Transplant seedlings when large enough to handle to 8cm pots and grow on. Acclimatise for 10-15 days before planting out.
