Venus Flytrap Summer Heat and Winter Dormancy in Phoenix, AZ

A Phoenix grower asked if Venus flytraps survive 4-5 months of 100°F+ highs, and if winter highs of 60-70°F/lows 30-40°F provide sufficient dormancy.

Heat Tolerance

Jacob Farin: flytraps wither above 100°F sustained; 110°F is max. Grow indoors during hottest summer, return outdoors when <100°F.

Phoenix winters are cool enough for brief dormancy. Growers keep plants outdoors successfully.
