How to grow Violet Queen Cleome seeds

Choose Your Planting Method

• Indoors: Start indoors 6–8 weeks before the last frost.
• Outdoors: Direct sow after all frost danger.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Cover with a humidity dome until sprouts appear.
• Spray bottle for misting

Sowing the Seeds

• Sow on the surface and press in — light is required for germination; cover with only a fine sprinkling of vermiculite.
• Optional: chill seeds in the refrigerator for 1–2 weeks before sowing to improve germination.

Provide the Right Conditions

• Light: Bright light.
• Temperature: 68–70°F (20–21°C).

Germination

• 10–21 days.
• Transplant carefully when small — cleome dislikes root disturbance.

Transplanting

• Set out after all frost danger when seedlings are a few inches tall.
• Harden off for 7–10 days before moving outdoors.
• Space 12–18 inches apart.

Care Tips

• Sun: Full sun.
• Water: Water regularly; established plants handle dry spells.
• Fertilizer: Light feeding; avoid high-nitrogen fertilizers, which favor foliage over flowers.
• Deadhead to prolong bloom; leave some seed pods if you want volunteers next year.

Bloom Time:

Summer to first frost.
