CLINTON

(Vulpina, Labrusca)

_Worthington_

Clinton (Plate X) came into prominence because of vigor, hardiness,
fruitfulness and immunity to phylloxera. A serious defect is that the
vines bloom so early that the blossoms are often caught by late frosts
in northern climates. Other defects are: the fruit is small and sour,
and the seeds and skins prominent. The fruit colors early in the
season but does not ripen until late, a slight touch of frost
improving the flavor. Clinton bears grafts well, making a quick and
firm union with Labrusca and Vinifera, and the vines are easily
propagated from cuttings. This variety has been used widely in
grape-breeding, and its blood can be traced in many valuable
varieties. The offspring of Clinton are usually very hardy, and this,
taken with its other desirable characters, makes it an exceptionally
good starting-point for breeding grapes for northern latitudes.
Clinton is an old sort, the Worthington, known as early as 1815,
renamed; it began to attract attention about 1840.

Vine vigorous, hardy, healthy, productive. Canes long, numerous,
slender, reddish-brown; nodes enlarged, flattened; shoots smooth;
tendrils intermittent, sometimes continuous, bifid. Leaves hang
until late in the season, small, thin; upper surface dark green,
smooth; lower surface pale green, glabrous; petiolar sinus deep,
narrow, urn-shaped; basal and lateral sinuses shallow; teeth wide.
Flowers self-fertile, open early; stamens upright.

Fruit mid-season. Clusters small, slender, cylindrical, uniform,
single-shouldered, compact; pedicel short, very slender, smooth;
brush tinged with red. Berries small, round, oval, purplish-black,
glossy, covered with thick bloom, adherent, firm; skin very
thin, tough, free from pulp with much wine-colored pigment,
astringent; flesh dark green, juicy, fine-grained, tough, solid,
spicy, sour, vinous. Seeds adherent, two, short, blunt, brownish.

COLERAIN

(Labrusca)

This is one of the numerous white seedlings of Concord and one of the
few with sufficient merit to be kept in cultivation. The vine has the
characteristic foliage and habit of growth of its parent, but the
fruit is earlier by a week, is of much higher quality and lacks the
foxiness of most Labruscas. The grapes are sprightly and vinous, and
neither seeds nor skin are
