Campsis radicans aka Trumpet Creeper

Campsis radicans, more commonly known as trumpet vine, yellow trumpet vine, cow itch vine or hummingbird vine, is a species of flowering plant in the family Bignoniaceae. Native to eastern North America, it is a very vigorous, deciduous and woody vine that can grow up to 10 metres (33 feet) tall. It is most commonly found inhabiting woodlands and riverbanks, but is also a popular garden plant. It has the great attribute of producing aerial roots, so it can live and cling to walls, trees and other structures. In the garden, it thrives in lean-to-average soils with regular moisture in full sun to partial shade, and blooms on new growth. When planted and supported, it can easily produce several flowering shoots of 4-6ft long each season. Pruning the vine back into shape is usually done in late summer or early in the springtime, and it is recommended that only a few shoots be chosen to be constrained, cut back and tied in, while the remaining shoots are removed entirely.
