Answer

Trumpet vine (Campis radicans) is a fast growing, woody vine with dramatic flowers. Hummingbirds are especially attracted to trumpet vine flowers. It is hardy in USDA zone 4-9. It will grow well in part shade but sun is necessary for good flower production.  Trumpet vine tolerates most soil conditions and does not need to be fertilized because of its vigorous growth. It can be grown against a wall  or on a trellis or pergola, . Because of their strong growth characteristics trumpet vines need to be severely pruned every year. This is bet done in late winter or early spring. Last year's growth should be cut back to two or three buds. This will not affect flower production as trumpet vines flower on new growth.

The only reason not to grow this attractive plant is its invasive nature. It will spread rapidly through suckering. and can easily take over a garden. If you decide to grow this species because of its many attractive features, try growing it in a concrete-lined pit or in a large container. You can also dig a trench around the tree (about 3 feet from the base of the tree). When grown in a lawn, regular mowing will help to contain its spread. In colder areas its invasiveness is less of a problem.
