 (Labrusca, Vinifera) 



Hercules is characterized by very large berries, fruit hand-

 while not of the best, is good. Added to the desirable qualities 

 of the fruit, the vines are hardy, vigorous and productive. 

 These good characters, however, cannot make up for the several 

 defects of the variety. The grapes drop and crack badly and

 purposes. Hercules was introduced by G. A. Ensenberger, 

 Bloomington, Illinois, about 1890; its parentage is unknown. 



Vine very vigorous, hardy, very productive. Canes long, dark 

 reddish-brown ; nodes enlarged, flattened ; internodes long ; tendrils 

 continuous, bifid. Leaves large ; upper surface light green, glossy,

 terminus acute ; petiolar sinus deep, narrow ; basal sinus usually
