Invasive Mile-a-Minute Vine Is No Slouch
As you might guess, mile-a-minute vine was named for its speedy growth, with the vines reaching 15 feet in a single growing season. Another name for it is "Asiatic tearthumb" because the vines are lined with hooked barbs that catch on skin and clothing. It's easy to identify because the leaves are shaped like equilateral triangles. The stems are often reddish and surrounded by cup-like leafy structures. Small spikes of colorful metallic-blue, pea-size fruits are held above the vines.
