History

The species name is dedicated to Mr. and Mrs. Coignet who reportedly brought seeds back from their trip to Japan in 1875.^{[citation needed]}

This vine was also reported in 1884 snowy regions of Japan by Henri Degron sent to East Asia to seek wild vines resistant to Phylloxera. Degron sent specimens to a Professor Planchon of Montpellier who named them Vitis coignetiae but did not retain them due to their low resistance to phylloxera. Degron planted a vineyard in Crespières, Île-de-France where one of the vines reached a length of 32.8 meters and a height of 2.8 meter. In the cooler Norman climate the vine produces a bitter wine, rich in color and extract.^{[citation needed]}

Description

The vine is very vigorous, with purple shoots. The deciduous leaves are large (15 to 30 cm in diameter), simple, orbicular, toothed, with deep petiole. First green, they turn red-orange in autumn.^{[citation needed]}

Wild vines can be male, female or hermaphrodite. Clusters are large with small berries and large purple seeds. It is found in the mountainous regions of Japan and up to 1300 m altitude in Korea.^{[citation needed]}

Uses

In East Asia it is grown as an ornamental plant for its crimson autumn foliage; and as an Oriental medicinal plant.^{[citation needed]}

It is a recipient of the Royal Horticultural Society's Award of Garden Merit.[3]

It is used to produce wines in Korea and Japan. These are at first bitter, but softened with the addition of sugar.^{[citation needed]}

Chemistry

The plant contains the stilbenoids ε-viniferin^{[citation needed]} and rhapontigenin.[4]
