Campsis radicans (trumpet vine or trumpet creeper), also known in North America as cow itch vine or hummingbird vine, is a species of flowering plant of the family Bignoniaceae, native to the eastern United States and naturalized in parts of the west as well as in Ontario and parts of Europe. Growing to 10 m (33 ft), it is a vigorous, deciduous woody vine, notable for its showy trumpet-shaped flowers. It inhabits woodlands and riverbanks, and is also a popular garden subject. I planted this in our yard 15 years ago and this is the first time I noticed the beautiful flowers and they extended 20 feet up the maple tree that is growing up.
