The clusters of dainty flowers on butterfly vine shine as brilliant as the summer sun. But it's the seed pods that give the plant its name.
During summer, chartreuse 'wings' unfold on the seed pods that look like butterflies. The papery pods will turn tan to brown as they mature, and they can be harvested and planted. It refers rich, well-drained soil. Plant the frost-tender vine on the south or east side for winter protection.
