(Labrusca, Vulpina)

Endowed with a constitution enabling it to withstand cold to which
most other grapes succumb, Janesville has made a place for itself in
far northern localities. Moreover, the grapes ripen early, being about
the first to color although they are not ripe until some time after
coloring. The vine also is healthy, vigorous and productive. The
fruit, however, is worthless when better sorts can be grown. The
clusters and berries are small, the grapes are pulpy, tough, seedy,
have a thick skin and a disagreeable acid taste. Janesville was grown
by F. W. Loudon, Janesville, Wisconsin, from chance seed planted in

Vine vigorous, hardy, healthy, productive. Canes spiny, numerous,
dark brown; nodes flattened; internodes long; tendrils
intermittent or continuous, long, bifid or trifid. Leaves small,
thin; upper surface glossy, smooth; lower surface pale green,
lightly pubescent; leaf usually not lobed with terminus acute;
petiolar sinus narrow, often closed and overlapping; basal and
lateral sinuses lacking; teeth shallow. Flowers self-fertile, open
very early; stamens upright.

Fruit early, keeps well. Clusters small, short, cylindrical,
usually single-shouldered, compact; pedicel short, slender,
covered with small, scattering warts; brush dark wine color.
Berries round, dull black with heavy bloom, persistent, firm; skin
thick, tough, adherent with dark wine-colored pigment, astringent;
flesh pale reddish-green, translucent, juicy, tough, coarse,
vinous, acid; fair in quality. Seeds adherent, one to six, large,
broad, angular, blunt, dark brown.
