Deep, dark, velvety red-violet flowers featuring the famous Sweet William fragrance are produced in clusters at the tips of the 18-inch flowering stems. The centers of the flowers are accented with tiny white stamens. Plant 'Sweet Black Cherry' in full sun, average soils, and close to a path or window to enjoy the fragrance. Sweet Williams are old-fashioned favorite perennials which are often used as annuals, especially varieties hybridized with other species. This cultivar was bred to produce flowers the first season.
