Passion vine, for the gulf fritillary butterfly
The passion vines most often seen here in Austin produce flowers that are blue or purple. These were grown from seen that came from Thompson & Morgan. There is a greenish tinge to the waxy and white-ish flowers. The scene is sharp.
Gulf fritillary butterflies leave their eggs among the vines, and, once they're on the move, the larvae consume the leaves. They require passion vines, whether the wild Maypop or some other type. The gulf fritillary butterfly, especially when it's resident in clouds, is just as spectacular as the passion flower.
