How to grow Sparkler Purple Cleome seeds

Choose Your Planting Method

• Indoors: Start indoors 4-6 weeks before the last frost.
• Outdoors: Direct sow after the last frost, when the soil has warmed.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Fine vermiculite (optional, to dust over the seeds)
• Spray bottle for misting

Sowing the Seeds

• Sow on the surface and cover with just a dusting of vermiculite — seeds need light to germinate.
• For indoor starts, chilling the sown pot in the refrigerator for 2 weeks can improve germination.

Provide the Right Conditions

• Light: Bright light; seeds need light to germinate.
• Temperature: 68-77°F (20-25°C).

Germination

• Germination takes 10-21 days.
• Be patient — cleome can be slow and uneven.

Transplanting

• Transplant carefully after the last frost; cleome dislikes root disturbance.
• Harden off before planting out.
• Space 12-18 inches apart in average, well-drained soil.

Care Tips

• Sun: Full sun.
• Water: Water until established; tolerates heat and dry spells once mature.
• Fertilizer: Generally not heavy feeders; compost at planting time is enough.
• Deadhead spent blooms to encourage more flowers and prevent heavy self-seeding.

Bloom Time:

Summer to fall.
