Overwintering Darlingtonia in a Canadian Fridge

Fridge Dormancy for Cobra Lilies in Cold Climates

If your winters drop well below freezing (central Canada), Darlingtonia must be protected. A refrigerator dormancy works well.

Protocol

• Leave stolons attached; they’ll survive.
• Repot in the same soil mix used during the growing season.
• Follow the Venus flytrap fridge dormancy guide—the steps are identical.
• Treat with a sulfur‑based fungicide before storage to prevent mold.
• Store at 35–40°F (2–4°C) for 3–4 months.

Coastal Canadians (e.g., Vancouver) may keep plants outdoors year‑round with minimal protection.
