Sarracenia Dormancy in Tropical Thailand: No Fridge Needed

A Thai grower (summer 89–100°F, winter 59–82°F) asked if Sarracenia, temperate butterworts, and sundews need artificial dormancy (fridge) or die in 2 years without it.

Key Findings

• Sarracenia: Enter a brief, natural 2-month dormancy (Dec–Jan) even in tropics. No fridge needed.
• Venus flytraps, temperate butterworts, temperate sundews: Require cold dormancy. Must use refrigerator (wrapped in damp sphagnum, 35–40°F, 3–4 months).
• Mexican butterworts (Pinguicula): Subtropical—thrive in Thailand year-round.
