In spring when all danger of frost is past and weather is warm and settled, sow seeds in a well-worked, fertile seed bed in full sun. Space seeds 2 to 3 inches apart in rows 12 inches apart, cover about 1/8 inch deep and firm soil gently. Keep soil evenly moist while awaiting germination in 12 to 28 days.
Four to five weeks before last frost date, sow seeds 1/8 inch deep and 2 to 3 inches apart in a container of seed starting mix. Keep warm and moist and provide a strong light source until seedlings are ready to plant outdoors. Seeds germinate best when day and night temperatures vary 10 to 20°. Thin or transplant seedlings 12 to 14 inches apart to give the large plants room to mature.
Tall old-fashioned Cleome is perfect to plant at the back of the border or in a cut flower garden combined with phlox, asters, snapdragons, cosmos or zinnias. Keep young plants well watered and weeded, and they will mature to handle dry heat or humid weather well and bloom all summer long.
