This is Passiflora tiliifolia. This is an extremely rare passion vine. The white and purple flowers are followed by a yellowish tan fruit which is edible and delicious. This is a host plant for the Zebra Long Wing, Zebra Heliconian, Julia Heliconian, Isabellas Heliconian, Banded Orange Heliconian, Mexican Fritillary, Scarce Bamboo Page, Erato Heliconian, Variegated Fritillary, and Gulf Fritillary butterflies. It is also a larval host plant for the Plebeian sphinx Moth. The hardiness is not known for sure but this plant may be suitable for subtropical zones so I am going to guess that it is USDA Hardiness Zones 9 to 11
