Vitis bicolor, Le Conte (V. argentifolia, Munson). Blue Grape, or Summer Grape of the N. Fig. 3964. A strong high-climbing vine, with mostly long internodes and thick diaphragms, the young growth and canes generally perfectly glabrous and mostly (but not always) glaucous-blue: tendrils and petioles very long: lvs. large, round-cordate-ovate in outline, glabrous and dull above and very heavily glaucous-blue below, but losing the bloom and becoming dull green very late in the season, those on the young growth deeply 3-5-lobed and on the older growths shallowly 3-lobed, the basal sinus running from deep to shallow, the margins mostly shallow-toothed or sinuate-toothed (at least not so prominently notch-toothed as in V. aestivalis): cluster mostly long and nearly simple (sometimes forked), generally with a long or prominent peduncle: the purple and densely glaucous berries of medium size (1/2 in. or less diam.), sour but pleasant-tasted when ripe (just before frost); seeds rather small. Abundant northward along streams and on banks, there taking the place of V. aestivalis. Ranges from New England and Ill. to the mountains of W. N. C. and to W. Tenn. —Well distinguished from V. aestivalis (at least in its northern forms) by the absence of rufous tomentum, the blue-glaucous small-toothed lvs. and long petioles and tendrils. It has been misunderstood because it loses its glaucous character in autumn; an excellent species as a covering for arbors and trellises.
