Are Passion Flowers evergreen???

No, deciduous. But in a mild winter and sheltered spot, the leaves on
P caerulea sometimes stay on till spring.

All are said to be evergreen to the exception of incarnata. The ones
that are semi-evergreen depending on the winter, is coccinea,
alatocaeruta and virifolia. My neighbour's P caerulea is evergreen
against a wall under a porch.
