Butterfly Vine is a Mexican native vine that climbs by twining and is notable for the seed pods which are shaped like butterflies. These are chartreuse and turn to tan and do look like green or brown butterflies. The pods are preceeded by clusters of showy yellow somewhat orchid-like flowers with five petals. This vine is evergreen into the 20's and deciduous at lower temperatures. In borderline areas it may freeze to the ground but will re-grow if protected with mulch. Plant in well-drained soil in full sun or semi-shade with a fence or trellis on which it can climb. It is quite drought tolerant but responds to regular watering.
USDA Hardiness Zone 8 - 10
