Family, Texas native, blooms mid-summer through early fall, can be an obnoxious weed

The quarter size(or less) chartreuse to pale green blooms have a slight sweet fragrance. It produces a green grape-like fruit which turns purple when ripe. You don't see these for long because the birds usually find them first. I am constantly pulling these vines up because they reseed themselves all over the place where I don't want them to be. They cover up other plants if they have no support. The plant is actually quite pretty, but I consider it an invasive weed in my cultivated gardens. It is on the endangered species list in Pennsylvania.

Gulf fritillary caterpillars love the leaves so I leave a few. These are young leaves and were damaged by a freeze. The leaves are usually a darker green.
