Sow seeds immediately you receive them at any time of the year into damp compost or seed raising mix just cover lightly with river sand or compost. Do not exclude from light. Germination is slow. After sowing seal container in a polythene bag and leave at 15-18 degrees C for 2 weeks, then place in the fridge (not freezer) for 3-6 weeks. After this period return to 15-18 degrees C. If germination does not occur in 6-10 weeks return to fridge for further 3-6 weeks. Check regularly whilst in fridge and remove immediately the seeds show signs of germinating. Pot on seedlings into 7.5cm pots when large enough to handle to harden and mature before planting out in the garden. Tricky but worth it.
