At the time of its introduction (1872) it was of much interest as a hybrid between Riparia, Labrusca and Vinifera, Clinton being one parent and Duke of Magenta, a grape resembling Black Hamburg, the other. In quality of fruit it is an improvement over Clinton but unfortunately, as with so many primary hybrids of our native species with _Vitis vinifera_, the vine is tender and susceptible to fungi. This variety was produced by J. H. Ricketts of Newburgh, New York, and was first exhibited at the grape show in New York City in 1870. Vine vigorous, productive, not very hardy, subject to attacks of mildew. Canes long, covered with considerable blue bloom. Leaves rather large, thin, dark green. Fruit ripens in mid-season, appears to keep well. Clusters above medium size, usually single-shouldered, the shoulder being connected to the cluster by a rather long stem, medium in compactness and with many abortive fruits. Berries medium to large, oval, dark purplish-black, covered with heavy blue bloom, persistent. Flesh somewhat tender, flavor sweet and spicy with considerable resemblance to that of Clinton, quality good. AGAWAM. (Labrusca, Vinifera.) =1.= _Mag. Hort._, =23=:86. 1857.
