Suffolk Red Seedless Grape is a selection of a hybrid cross between Russian seedless (a Vitis vinifera hybrid) and a cultivar of American Fox Grape (Vitis labrusca). It is hardier than European grapes, requires less heat to ripen than most grapes, and produces the largest berries of the hybrids. It only requires 100 chill hours, so basically it can be grown anywhere in the U.S. and many parts of Canada. The fruit quality is excellent, and usually ripen early among grape cultivars.
Now as you might have read, we are having some unusually warm daytime temperatures here in San Diego for December. My poor Suffolk Reds are confused, and sporting fruit buds as if it is spring!
