Cleome seeds do not require light for germination, but should be pre-chilled in the fridge at 40°F for at least 5 days prior to planting. Plant in an area with well-worked soil and at least morning and early afternoon sun; cover the seeds lightly and water very gently, but thoroughly, keeping them moist until sprouting. At soil temperatures above 70°F, Cleome normally takes about 10 days to germinate. Consistent moderate moisture will produce the best results as the plants mature. Plant 1-3 inches apart, thinning to 15-18 inches. If you wish, start indoors to transplant to get a jump start and then plant outdoors when all danger of frost has passed.

Comment: These beautiful cleome crowns reseed themselves and bloom all season. Doesn't get any better than that. Love them.
