Timing:
Start indoors from 6-8 weeks prior to the last frost date for transplanting (or simply direct sow) 3-4 weeks after last frost. If direct sowing, consider repeating every two weeks into early summer for a longer bloom period. Seeds will sprout in 10-14 days.
Starting:
Sow on the surface of the soil. If starting indoors, seeds benefit from vernalization: Place seeds on the surface of moistened, sterilized seed starting mix in pots, and place pots in zip-top plastic bags inside the refrigerator for 2 weeks. Then move pots to bottom heat and maintain soil temperature at 21-25°C (70-75°F) until germination. Provide bright light.
Growing:
Cleome is quite an undemanding annual. The stems are usually very strong and upright, but might benefit from support in very windy, exposed gardens.
