‘Sweet Summer Love’ clematis is the hot weather cousin to sweet autumn clematis, a classic fall bloomer that opens sweetly scented flowers. ‘Sweet Summer Love’ clematis unfurls flowers all summer long—from July through September—that exude a sweet fragrance. On hot humid days, the scent hangs deliciously in the air. Blossoms start a cranberry hue and shift to purple as they age. Best of all, ‘Sweet Summer Love’ won’t invade your garden with unwanted seedlings (like its cousin, sweet autumn clematis). Plants benefit from a hard pruning (cut stems to 6 inches tall) in late winter. Vines grow 10 to 15 feet tall and 6 to 10 feet wide—a great choice for an entry arch or trellis. Hardy in Zones 4-9.
