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. In mild winters, the vine will retain its gloss green foliage. It will die back and resprout in spring after a cold winter. The plant recently was renamed; it previously was classified as Stigmaphyllon ciliatum.
Water newly planted vines until they are well established. While it is drought-tolerant, the yellow butterfly vine does look better with regular watering during dry spells.
Every spring, apply a slow-release 3-1-2 fertilizer to the vine. This application improves its flowering and growth.
If grown in a container, make sure the pot is at least 20 inches in diameter and has a pole or trellis-like support to keep it upright.
