    Butterfly vine seeds need a little scarification—rub them with sandpaper or nick them with a knife—then soak them overnight. Plant in well-draining soil after the last frost, in full sun. In zone 7-7A, it might die back in winter but can return in spring if mulched well. Treat it as a perennial with some winter protection or an annual if you don’t want the hassle. Fast grower, loves heat—should thrive!
