Venus Flytrap and Sarracenia Dormancy in South Florida (Zone 10): No Fridge Needed

In South Florida (Zone 10), you don't need to force dormancy with a refrigerator. Natural cues are sufficient.

Why Natural Dormancy Works in Zone 10

• Photoperiod: Daylight hours decrease enough to trigger light dormancy.
• Temperature fluctuations: Periodic cool spells (even if brief) provide temperature cues.
• Contrast with Zone 11: Key West/Honolulu (Zone 11) lack these cues; Zone 10 does not.

Species-Specific Notes

• Sarracenia purpurea ssp. venosa (common in cultivation) handles short dormancy well.
• S. purpurea ssp. purpurea may struggle—less common in trade.
• Venus flytraps usually do fine; observe rather than risk fridge dormancy (which can kill unacclimated plants).
