Crossvine is a large, tropical-looking vine related to trumpet creeper (Campsis) but better behaved and semi-evergreen. Growth is rapid and can cover a large trellis or pergola. Can also climb up tree-trunks just like Virginia Creeper. Runners are few and above ground, so easily controllable. Large, orange and yellow flowers appear April-May and attract hummingbirds. Preference is for part sun and average garden soil. Zone 5-9. Unknown ecotype.
