Campanula pyramidalis (Chimney Bellflower)

Mix seeds with moist sand or a damp paper towel inside a sealed plastic bag.
Store in the refrigerator at 35–40°F (1–4°C) for 2–4 weeks.
Check weekly: If seedlings sprout in the fridge, remove them gently and plant immediately.
Ensure they remain moist but not waterlogged.

Best Sowing Time: Early spring (indoors) or late spring/early summer (outdoors).
Seed Depth: Do not cover with soil—light is needed for germination.
Soil: Well-draining, loamy or sandy soil with a pH of 6.0–7.5.
Light Requirement: Full sun to partial shade.
Moisture: Keep soil evenly moist but not waterlogged.
Temperature: Germination occurs best at 68–72°F (20–22°C).
Germination Time: 14–40 days.

Once seedlings have 2–3 sets of true leaves, thin or transplant them to their final location.
Space plants 12–18 inches apart for healthy growth.
Water regularly until established, then reduce watering (drought-tolerant when mature).
Deadhead spent flowers to prolong blooming.
