(Labrusca, Vinifera)
Jessica is an early, hardy, green grape. The fruit is sweet, rich, sprightly and almost free from foxiness, but is unattractive and does not keep well. The clusters and berries are small, and the clusters are too loose for a good grape. Jessica may be commended for earliness and hardiness and is, therefore, desirable, if at all, in northern regions. William H. Read, Port Dalhousie, Ontario, grew Jessica from seed planted some time between 1870 and 1880.
Vine medium in vigor, healthy, hardy, productive. Canes long, thick, dark brown with red tinge; nodes enlarged, flattened; internodes short; tendrils continuous or intermittent, bifid or trifid. Leaves small; upper surface dark green, glossy, often rugose; lower surface pale green, very pubescent; lobes three; petiolar sinus narrow; teeth shallow, narrow. Flowers self-fertile, open in mid-season; stamens upright.
Fruit very early. Clusters small, slender, tapering, usually single-shouldered. Berries small, round, light green, often tinged with yellow, covered with thin bloom, persistent, soft; skin thin, adherent, faintly astringent; flesh pale green, transparent, juicy, tender, soft, sprightly, sweet; good. Seeds adherent, medium to broad, notched, brown.
Jewel
(Labrusca, Bourquiniana, Vinifera)
The notable characters of Jewel are earliness and high quality in fruit; although, as compared with Delaware, its parent, the vine is vigorous, healthy and hardy. In form and size of bunch and berry, Jewel closely resembles Delaware, but the grapes are deep black in color. The flesh characters and flavor of the fruit are much like those of Delaware, the pulp being tender yet firm, and the flavor having the same rich, sprightly, vinous taste found in the parent. The seeds are few and small. The skin is thin but tough, and the grapes ship well, keep long, do not shell, and although early, hang until frost. Jewel is a most excellent grape, worthy the place among black grapes that Delaware has among red varieties. In particular, it is recommended for earliness and for localities in the North where standard varieties do not ripen. John Burr, Leavenworth, Kansas, grew Jewel from seed of Delaware planted about 1874.
Vine vigorous, healthy, hardy, productive. Canes slender, light reddish-brown; nodes enlarged, flattened; internodes short; tendrils continuous, bifid. Leaves scant, thick; upper surface light green, dull, rugose; lower surface tinged with bronze, heavily pubescent; lobes three when present with terminus acute; petiolar sinus narrow; basal sinus usually lacking; lateral sinus shallow, wide; teeth shallow. Flowers self-sterile, open in mid-season; stamens reflexed.
Fruit early. Clusters small, slender, cylindrical, single-shouldered, compact; pedicel short, slender; brush short, wine-colored. Berries medium in size, round, dark purplish-black, dull with heavy bloom, persistent, firm; skin thin, tough, adherent, wine-colored pigment; flesh pale green, translucent, juicy, fine-grained, tender, sprightly, vinous, sweet; very good. Seeds adherent, one to four, frequently one-sided, blunt, light brown.
