Start indoors 6-8 weeks prior to last frost or can be planted direct. Sow on the surface of a good free-draining growing mix. Cover seeds lightly. Seal in a polyethylen bag at about 16-21 degrees C (60-70 F) until germination. Transplant to 8 cm (3") pots when large enought to handle. Plant outdoors when all risk of frost has passed.
