Cleome often self-seeds readily, although cultivars may not produce progeny the same as the parent plant (and after several generations all end up a pale pink color). Removing the seedpods as they develop can help limit self-seeding or spreading thick mulch over the area the following spring will reduce volunteers.

Does cleome come back every year?

Planting cleomes is often necessary only once, as this attractive annual flower re-seeds prolifically and returns year after year. Seed pods may be removed before bursting for use in planting cleomes in other areas of the flower bed and garden.

How do you reseed cleome?

Direct sow Cleome seeds in average soil in full sun after danger of frost. Prepare the soil for Cleomes by removing weeds and working organic matter into the top 6-8 inches of soil; then level and smooth. Most annual flower plants respond well to soils amended with organic matter.
