Yellow Passionflower Vine

A native vine with small, intricate green flowers. Uncommon in the nursery trade but may volunteer in yards in Northern San Antonio. Homeowners lucky enough to have one growing in their landscape are often unaware of this unassuming but important plant. Its fruits are attractive to birds and it is the larval food source for the orange and black Gulf Fritillary butterfly caterpillar. The caterpillars look spiky but are harmless – let them munch away on the leaves if you want beautiful orange butterflies in summer and fall.
