Can be sown indoors or outside in flowering position.
Indoors: Sow at any time of year very thinly on the surface of a good, free draining damp seed compost and lightly cover with sieved compost. Seal inside a polythene bag, place on a sunny windowsill or in a propagator and maintain at 15-18C. Germination can take 30-60 days or perhaps longer and can be erratic hence the need to sow the seeds as thinly as possible. Check the container regularly to make sure the compost does not dry out.
Outdoors: Prepare the soil by removing any weeds and raking to a fine tilth. Sow the seeds, press lightly into the soil and cover with a fine sprinkling of soil. Keep the soil moist but not waterlogged and germination will take 30-60 days. Thin the seedlings to 30cm apart as necessary.
