Commonly called crossvine, Bignonia capreolata is native from Southern Ontario extending into the eastern U.S. It is disease resistant and easily grown. This vine, a Plant of Merit for 2013, prefers average, medium, well-drained soil in full sun to quite dense shade. In all but the most severe winters, this vine is evergreen and hardy. Should we have very cold weather, it could be killed back to the roots but should return from new shoots. Mulch helps eliminate most winterkill.
The showy bell-shaped flowers are orange-red and occur May to June. It is attractive to hummingbirds and very fragrant. It climbs by twining and climbs 35 to 50 feet. Bignonia capreolata produces many shoots but its spread can be curtailed by pruning those that are not wanted.
