The fruit of Black Eagle is of the best, but the vine lacks in vigor,
hardiness and productiveness and is self-sterile. Bunch and berry are
large and attractive. The season is about with Concord. Black Eagle
has wholly failed as a commercial variety, and its several weaknesses
prevent amateurs from growing it widely. The variety originated with
Stephen W. Underhill, Croton-on-Hudson,
ew York, from seed of Concord
pollinated by Black Prince. It fruited first in 1866.
Vine vigorous, precariously hardy, unproductive. Canes rough,
thick, reddish-brown with light bloom; nodes enlarged, flattened
internodes long; tendrils continuous, long, bifid or trifid.
Leaves thick; upper surface dark green, glossy, smooth to rugose;
lobes five; terminal lobe acute; petiolar sinus deep; lateral
sinus wide, narrowing towards top, deep. Flowers open in
mid-season, self-sterile; stamens reflexed.
Fruit mid-season, keeps well. Clusters large, long, tapering,
single-or double-shouldered, compact; pedicel long, slender with
few warts; brush short, pale green. Berries variable in size,
oval, black, glossy with thick bloom; skin tender, thin, adherent
with wine-colored pigment; flesh pale green, translucent, tender,
vinous; good. Seeds free, one to four, large.
