- Sow February to June or September to October.
- Sow on the surface of a good, free-draining, damp fine seed compost. Do not cover the seeds as light aids germination, but gently press into the compost.
- Best sown in a propagator for moisture retention or seal inside a clear polythene bag at 16 to 20°C.
- Germination usually takes 14 to 30 days.
- Transplant to individual (3in) pots when large enough to handle and grow on under cover.
- Overwinter autumn sown seedlings in a coldframe and plant out the following spring.
