North America from southernOntario east toVermont , west toOklahoma , and south toFlorida andTexas .Germplasm Resources Information Network: [http://www.ars-grin.gov/cgi-bin/npgs/html/taxon.pl?311851 "Vitis aestivalis"] ] It is a vigorousvine , growing to 10 m or more high intree s. The leaves are 7–20 cm long, suborbicular, and usually a little broader than long; they are variable in shape, from unlobed to deeply three- or five-lobed, green above, and densely hairy below. Theflower s are produced in a densepanicle 5–15 cm long. Thefruit is a smallgrape 5–14 mm diameter, dark purple or black in color.Oklahoma University: [http://www.biosurvey.ou.edu/shrub/viaea2.htm "Vitis aestivalis"] ]There are four varieties:
*"Vitis aestivalis" var. "aestivalis".
*"Vitis aestivalis" var. "bicolor" Deam (syn. var. "argentifolia" Fernald; Silverleaf Grape), formerly called "Vitis bicolor", but now considered a northern variation of "Vitis aestivalis". Native range is in theNortheastern United States and parts ofSouthern Ontario .
*"Vitis aestivalis" var. "lincecumii" (Buckley) Munson.
*"Vitis aestivalis" var. "bourquiniana", native to the south, sometimes called "Vitis bourquiniana", hastomentose undersides to the leaves.Cultivation and uses
Several cultivars have been selected, including 'Norton', a cultivar with a substantial "V. aestivalis" background, is believed to be the oldest American grape cultivar in commercial production.
Selections of "V. aestivalis" such as Norton, and inter-hybrids made with the species have shown several useful traits for commercial
wine production when compared other North American native grape varieties. These traits include: lower acidity, neutral, "vinifera-like" flavour profile, good tannin structure, and excellent disease resistance.Unlike most other species in genus "vitis", "V. aestivalis" does not propagate well through dormant cuttings. This has been a limiting factor for its use in commercial viticulture despite the species' promising oenological characteristics. Propagation of "V. aestivalis" specimens must typically be made through
layering or through green cuttings. The species typically does not tolerate highly calcareous soils. Appellation America: [http://wine.appellationamerica.com/grape-varietal/Norton-%7C-Cynthiana.html "Norton / Cynthiana"] ]It has been claimed that a variety of Vitis aestivalis was cultivated by the
Cherokee s and used in some of their sacred rituals.cite book | author= Mooney, James | title=History, Myths, and Sacred Formulas of the Cherokees| publisher=Historical Images | year=1992 | id=ISBN 0-914875-19-1]References
