Sweet Autumn Clematis
While clematis cultivars come in many beautiful colors, with both single and double flowers, one of my favorite varieties is the old stand-by sweet autumn clematis. As its name implies, sweet autumn clematis blooms in late summer or early fall and has sweet, vanilla-scented blossoms. Its huge masses of flowers often hide the leaves almost entirely. One plant climbing into our blue spruce sends up vines as high as twenty feet. While impressive during the day, it's spectacular at dusk, when its blossoms literally glow against the darker needles of the spruce.
