Sow indoors or under glass in spring, sow into a cold frame in autumn. Indoors, surface sow onto moist well-drained seed compost. Just cover with grit. Place somewhere cool, ideal temp. 15-22°C. Germination takes 21-40 days. Germination can be erratic taking much longer. If germination does not occur cold stratify. Move to 4°C, a fridge is ideal, for 4-6 weeks then return to warmth for germination. When seedlings are large enough to handle transplant to 8cm pots and grow on. Acclimatise and plant out after danger of frost has passed. Can be sown into a cold frame in autumn where winter cold should offer ideal conditions for germination to occur in spring as the weather warms.
Prefers a damp soil with plenty or added organic matter in partial sun. Requires little attention. Roots must not dry out.
