Life Cycle This refers to whether a plant is an annual, biennial or perennial. Annuals complete their life cycles in one year; biennials produce foliage the first year and bloom and go to seed the second year; perennials can live for more than two years.
Sow Method This refers to whether the seed should be sown early indoors and the seedlings transplanted outside later, or if the seed should be sown directly in the garden at the recommended planting time.

Sowing Cleomes Directly in the Garden:
- 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. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
- Sow seeds thinly and cover with ¼ inch of soil.
- Firm soil lightly and keep evenly moist.
- Seedlings will emerge in 14-21 days.
How to Direct Sow Cleome Seeds
- Thin Cleome flower plants to stand 8 inches apart when plants are 1 to 2 inches high. Thin again to 2 feet apart when plants are established.
- Keep weeds under control during the Cleome growing season. Weeds compete with annual flower plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
- Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
- Keep soil evenly moist but not wet. Fertilize as needed with a slow release fertilizer designed for flowering plants.
- Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
- Plants can self-sow, so allow some to set seeds.
- Remove plants after they are killed by heavy frost in fall to avoid disease issues the following year.
- Cleome annual flowers are easy to grow and need little care.
- Cleomes make striking, fast-growing annual hedges. Their thorns and dense foliage create an effective barrier, while prolific blooms create a pleasing mass of color.
- Add tall varieties to the back of an annual, perennial or mixed border for their long bloom periods and airy flower heads. You can use them to fill in between clumps of perennials, and they combine well with many shrubs.
- Cleomes also make interesting cut flowers.
