One of our favorite summer bloomers is the deliciously fragrant Summersweet. Long panicles of tiny white blossoms grace this shrub July to August, perfect for butterfly or fragrant gardens. This gorgeous cultivar selected by Fred Galle at Calloway Gardens is compact to 3-4' and even more free-flowering than the species! This special plant would be a welcome addition to any garden.
