How to grow Rose Queen Cleome seeds

Choose Your Planting Method

• Indoors: Start seeds indoors 4–6 weeks before the last frost.
• Outdoors: Direct sow outdoors after all danger of frost has passed.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Spray bottle for misting

Sowing the Seeds

• Sow on the surface of moist mix and press in gently — do not cover; cleome seeds need light to germinate.
• Optional: 2 weeks of cold, moist stratification in the refrigerator can speed germination.

Provide the Right Conditions

• Light: Bright light during germination.
• Temperature: 68–77°F (20–25°C).

Germination

• Expect sprouts in 10–21 days.
• Keep evenly moist until germination.

Transplanting

• Transplant after frost when seedlings are sturdy.
• Harden off for 7–10 days before planting out.
• Space plants 12–18 inches apart.

Care Tips

• Sun: Full sun.
• Water: Water regularly; established plants handle short dry spells.
• Fertilizer: Not a heavy feeder.
• Deadhead spent blooms to encourage more flowers and limit self-sowing.

Bloom Time:

Summer through fall, until the first hard frost.
