When to plant Crossvine
Crossvine is a vigorous tendril-climbing native vine that blooms early, in late winter to early spring (NC State), with orange-to-red trumpet flowers that are an important early food for hummingbirds. Plant in spring or fall on a sturdy support; it blooms on new wood, and flower production improves with more sun.
