'Somerset' Seedless Grape'
Who wants to have to spit out seeds? 'Somerset' is the earliest, hardiest, high-quality seedless grape available. Bred by noted Wisconsin grape breeder Elmer Swenson, this red variety produces small to medium size clusters of medium size grapes with a strawberry-like flavor. Fruits are edible at their pink stage in August, but are sweetest if ripened to their full red color. The vine is hardy to -30 F and shows good disease resistance, but may need spraying to control powdery mildew.
