This hybrid benefits from the relative frost hardiness of its parent P. caerulea. But its other parent, P. alata, is more tender and will die below about 28°F. (-2°C) In practice, this vine should survive brief frosts down to about 21-26°F (-3 to -6°C).

Soil - Like most passion flowers, this hybrid needs a well-drained soil.
