Trumpet Vine Campsis radicans

Campsis radicans 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. but has naturalized in many northern states.

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.

It 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 part 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 problem with species plants (Campsis radicans) 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 in the wild which can choke out many plants that get in their way.
