There was an unusual freeze here in the winter of 2007. On mature plants:
- 3 hours pre-dawn at 27F in my yard caused a few leaves to get brown edges. It flowered the following week. In contrast, my passiflora quadrangularis was dead.
- 3 hours pre-dawn at 23F farther inland caused significant leaf drop but it re-grew within a few months.
- 3 hours pre-dawn at 18F in the mountain foothills killed the plant.
