Vine not vigorous, lacks in hardiness, an uncertain bearer, unproductive. Tendrils continuous, bifid. Leaves medium to small, inclined to dark green, thick. Flowers vary from nearly fertile to almost sterile, open in mid-season; stamens upright. Fruit ripens as early as Champion. Clusters variable in size, usually short and not shouldered, not uniform in compactness. Berries medium to large but some years often small and seedless, much like Isabella in shape, unattractive in color, ranging from dull reddish-purple to blackish, covered with blue bloom. Flesh tender, vinous, mild from skin to center, variable in flavor and quality, ranking from fair to very good. The seed-coat is often rough and warty. CENTENNIAL.

Centennial is now scarcely heard of though at the time of its introduction, shortly after the Centennial of 1876, it was looked upon as a valuable acquisition. Its chief meritorious attributes are high quality and attractive appearance; while its faults, which greatly outweigh its merits, are lack of vigor, susceptibility to fungi, and lack of hardiness. Centennial is much like Delaware and is surpassed by it in nearly all respects. The variety was originated by D. S. Marvin, of Watertown, New York. It is a cross between a Labrusca seedling of Marvin's and a seedling of Eumelan. It was first fruited in 1875, and was introduced in 1882 by the originator. Vines were received by this Station in 1883. The tenderness and lateness of ripening of Centennial, as well as its botanical characters, indicate Vinifera blood. The following description is a compilation from several sources: Vine vigorous, somewhat tender, fairly productive. Leaves rounded, slightly three-lobed, smooth. Clusters medium to small, compact, tapering or cylindrical, sometimes slightly shouldered. Berries medium to small, pale red or amber color with thin white bloom, adhere firmly to pedicel. Skin rather thick, tough. Flesh tender, juicy, sweet, resembling Delaware in flavor, good to very good. About the same season as Concord. CHALLENGE. (Labrusca, Vinifera?)
