(Frost Grape, River Grape, Spanish Grape)
Vitis riparia, Vitis berlandieri
The Frost or River Grape and Spanish Grape (the term "wild grape" will be used, too, covering both species) have extremely healthy yet "genuine" vine leaves. They are easy to care for and are particularly suited for decorative purposes; they create a "wine-atmosphere" without much maintenance. They won't develop fruits / grapes, so problems with usual grape vines, such es wasps, birds etc. are avoided!
Sunny (full sun) to (semi-)shaded position, will develop more intense yellow autumn colours in the sun.
A climber with tendrils, vigorous growth, yearly growth up to 1-4metres, may also cascade like a bridal train. Foliage from May to October.
Flower and Fruit
Inconspicuous green-yellow flowers in early summer, insignificant or no fruit at all. Advantage: problems which can occur in ripening and ripe (wine-) grapes are avoided.
Summer and winter pruning as needed, to restrain the vigorous growth habit and to prevent the plants from becoming straggly. Best trained as cordons with spur pruning as for the wine grape.
