The Purple Invasion
It climbs up trees, shrubs and anything that will serve as a support.
|Chinese Wisteria covering tree|
Chinese Wisteria was introduced to the United States in the early 1800's for ornamental purposes. It is found extensively throughout the eastern U.S. In the South it is often seen decorating porches and gardens. It is from these landscape plantings that they have naturalized and aggressively taken over.
Wisteria prefers moist soil and is shade tolerant but ideally likes sun for its prolific violet-blue flowers which only bloom during the plants transition from a young plant to adult. Since wisteria can live as long as 100 years this transition can take many years.
As it grows it twines upward in a clockwise direction cutting into the bark of the host tree eventually girdling and killing the tree. The weight of these vines can also topple large trees.
Just look at the size of this vine! Poor tree!
If you find Wisteria growing in your garden be mindful to control it or better yet remove it entirely making sure to get all the roots to prevent resprouting.
