Vitis Labrusca — “Isabella Grape.”
This variety of grape was early introduced to these Islands, and has become very popular. It is a hardy vine, variable in productiveness, and is practically the only grape grown in any quantity in Hawaii. The leaves are of medium size, often roundish and thick; their upper surface is dark-green, the under surface is whitish-green. The Isabella is an attractive blue-black grape, bearing in large, well-formed clusters, having a thick bloom. The muskiness of the thick skin is somewhat objectionable.
