Trumpet Vine

Campsis radicans (KAMP-sis RAD-ih-kans)

Family: Bignoniaceae Native Vine (vertical)

Trumpet vine is a dense, vigorous, woody, deciduous, perennial vine in the trumpetvine family (Bignoniacea) that attaches itself to structures and climbs by aerial rootlets. It is native to the central and eastern United States. In nature, it can be found in swamps, forests, thickets and on roadside telephone poles. The genus name comes from the Greek word kampe meaning “bent” in reference to the bent stamens of the flowers. The species epithet is Latin for “producing roots” and references the mode of climbing. Trumpet vine is easily grown in a wide variety of soils. It is best planted in lean-to-average soils with regular moisture in full sun to partial shade. Foliage grows well in shade, but plants need good sun for best flowering. It blooms on new growth, so early spring pruning will not affect the flowering. Vines must be grown on sturdy structures because mature plants produce considerable weight. The challenge with species plants is usually not how to grow them but how to restrain them, in large part because they sucker profusely from underground runners and freely self-seed, often forming impenetrable colonies that can choke out other plants. To keep it in check, plant it near concrete or an area that you can mow; mowing down the suckers will discourage them. Trumpet vine is the larval host for the plebeian sphinx moth . Good landscape uses include planting it in a woodland garden or naturalized area. It is also appropriate in native and pollinator gardens. Fire Risk: This plant has a high flammability rating and should not be planted within your home's defensible space. Select plants with a low flammability rating for the sites nearest your home. Insects, Diseases, and Other Plant Problems: No serious insect or disease problems, however, the species is an aggressive spreader. 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.
