The Hummingbird Vine is a vigorous grower that is native to the woodlands of the Southeastern United States but does well across much of the country. It is hardy to as low as -30F/-34C. Outside of its native range, the plant can become very invasive.
Extreme pruning is recommended. Skin contact can cause irritation and allergic reactions in some people. Wear the glove when pruning or handling the Vine.
The leaves are dense, ovate, and pinnate. New leaves are an emerald green but mature into dark green. In warm weather, it sprouts large amounts of tendrils that cling to any nearby surface. These will expand into thick woody stems several inches around.
The beautiful flowers from this vine will attract large numbers of hummingbirds and butterflies, along with many other birds like to nest in dense foliage.
This Vining plant will cover almost any kind of surface including- brick walls, polls, fences, arbors, and trees. Its roots are aerial and can cling to anything. Great for natural area gardening.
Tip for mild winter areas: Because the vine can become invasive (and painful to destroy should it happen)in more temperate climates some people, to prevent this problem, have cut out the bottom of a large planter and planted the vine underground inside the planter.
