How to grow Purple Campanula Bellflower seeds

Choose Your Planting Method

• Indoors: Start seeds 6-8 weeks before the last frost.
• Outdoors: Sow directly after the last frost, or in fall for blooms the following year.

Prepare Your Materials

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

Sowing the Seeds

• Sow on the soil surface and press in gently, or cover very lightly - light is required for germination.
• Mist to water so the tiny seeds are not displaced.

Provide the Right Conditions

• Light: Bright light; seeds need light to germinate.
• Temperature: 65-68°F (18-20°C).

Germination

• Seedlings typically emerge in 7-14 days.
• Keep the mix evenly moist and give seedlings strong light to prevent legginess.

Transplanting

• Transplant after the last frost once seedlings have several true leaves; harden off first.
• Space plants 10-12 inches apart.

Care Tips

• Sun: Full sun to partial shade.
• Water: Keep soil evenly moist; mulch helps retain moisture.
• Fertilizer: Not heavy feeders - compost worked into the bed at planting is enough.
• Deadhead spent spikes to tidy plants; allow some seed to drop if you want self-sown seedlings.

Bloom Time:

Late spring to early summer of the second year.
