No Carnivorous Plant Survives 120°F: Choose Heat-Tolerant Species or Cool the Conservatory

Reality Check

120°F (49°C) kills all carnivorous plants. Even the most heat-tolerant (VFT, Sarracenia) max out at 110°F for short periods with ample water.

Best of Your List

Drosera binata and D. rotundifolia are most heat-tolerant but still fail above 100°F sustained.

Water & Insect Digestion

• All need constantly wet soil (1/4 pot depth).
• Darlingtonia requires cool running water—impractical here.
• Insects are never fully digested; chitinous exoskeletons remain.

Solution

Install evaporative cooling/shade to keep conservatory below 95°F, or grow non-carnivorous heat-loving plants.
