It may not be the next kudzu, but it is well on its way. You’ve probably noticed the waterfalls of white blossoms hanging from the trees and draped over shrubs and brush on the sides of the road. The pure white blossoms glow against the faded, tired foliage of summer. Unfortunately, this is the most likely invasive Sweet Autumn Virgin’s Bower, scientifically, Clematis terniflora. It is in full bloom right now in Lee County, and now is the time to act to remove the vine! The flowers can guide you to where the vine comes out of the ground.
But it is so pretty!
The Sweet Autumn Virgin’s Bower was brought into North America from Asia because of its dense flowering habit and vigorous growth rate. It grows quickly even in challenging soil conditions, and tolerates a wide range of light conditions. The vine flowers at a time when summer is fading and fall is coming into focus. Garden-wise, there usually aren’t many things flowering when the Sweet Autumn Virgin’s Bower is, making it great for providing garden interest during a flower lull. Many native pollinators and honey bees will visit the flowers for pollen and nectar, too.
Even still, it is important to not get hung up on its beauty. Invasive species, no matter how beautiful, cause real ecological and economic damage.
Not to be confused with...
Horticulturists at the time didn’t realize there was a comparable native species, Clematis virginiana, the Virgin’s Bower, already here. While its flowering isn’t as dense as the invasive species, it is still very tolerant of a wide variety of growing conditions. It is now hard to find because of our diligent mowing habits on the sides of roads and on cleared land.
There is a major difference between the invasive and native species, though! Makesure to check the leaves before you start removing the vines so you don’t accidentally pull up or treat the wrong species with herbicide. The leaf margins, or edges of the leaves, of the invasive species are smooth and round, while the native species’s leaves have teeth or zig-zag-like edges. The leaves of Clematis terniflora, the invasive species, are also more glossy and shiny, while our native Clematis virginiana has a more matte, dull green color.
