Vitis labrusca — fox grape

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

Fox grape differs from its close relatives in that it produces tendrils from most of its nodes. Its leaves are also fuzzy with brown-gray hairs on the underside. Concord grapes (the purple ones used to make grape juice and jelly) are a cultivar derived from this species.

Habitat

Anthropogenic (man-made or disturbed habitats), forest edges, forests, meadows and fields, shores of rivers or lakes

2.  Vitis labrusca L. N

Fox grape. Vitis labrusca L. var. subedentata Fern. • CT, MA, ME, NH, RI, VT. Forests and forest borders, roadsides, clearings, river banks.

2×4. Vitis labrusca × Vitis riparia → Vitis ×‌novae-angliae Fern. is an uncommon grape hybrid known from CT, MA, ME, NH, RI, VT. It is distinguished by its abaxially tomentose young leaf blades that become glabrate in later season (sometimes with patches of tomentum remaining), tendrils and/or panicles produced from 3–5 successive nodes, and berries 12–17 mm thick.

Native to North America?

Yes

Sometimes confused with

Vitis aestivalis:
tendrils and/or inflorescences produced from no more than 2 consecutive nodes and berries 5-14 mm thick (vs. V. labrusca, with tendrils and/or inflorescences produced from 3-7 consecutive nodes and berries mostly 10-20 mm thick).
Vitis riparia:
tendrils and/or inflorescences produced from no more than 2 consecutive nodes and leaf blades sparsely hairy on the lower surface, the green surface clearly visible (vs. V. labrusca, with tendrils and/or inflorescences produced from 3-7 consecutive nodes and leaf blades densely hairy on the lower surface with red-brown to gray hairs, the surface concealed).
