PhenologyFlowering and fruiting July-October.
IdentificationVery few of our composites (Asteraceae) are vines; this is by far the most numerous. Vines climb or scramble up to 10 feet long (or more), with long-stalked, opposite, ovate, long-pointed leaves that have wavy margins and heart-shaped bases. Inflorescences are produced from leaf axils, are dome-shaped clusters up to 3 inches across, pale pink to white, all disk florets. These flowers are heavily used as nectar sources by a great array of insects.
