Campsis radicans, commonly called trumpet vine or trumpet creeper, is a dense, vigorous, multi-stemmed, deciduous, woody, clinging vine that attaches itself to structures and climbs by aerial rootlets. It is native to the southeastern U. S. including Missouri, but has naturalized in many northern states. In Missouri, trumpet vine is native to the Ozark region, but has naturalized throughout the State where it now typically occurs in woods, thickets, fields and along streams, roadsides and railroad tracks (Steyermark). Species plants rapidly grow to 30-40' high. Compound, odd-pinnate leaves (to 15” long) are shiny dark green above and glabrous dull green below. Each leaf has 7 to 11 elliptic to oblong leaflets (to 4" long) with serrated margins. Leaves turn yellow in fall. Clusters (terminal cymes) of red trumpet-shaped flowers (to 3” long) appear throughout the summer (June to September). Flowers are very attractive to hummingbirds. Flowers are followed by long, bean-like seed pods (3-5” long) which split open when ripe releasing numerous 2-winged seeds for dispersal by the wind. Trumpet vine is also commonly known as cow-itch vine because some people experience skin redness and itching after coming in contact with the leaves.
