The Flame Seedless (Viti vinifera) is a vigorous, heavy-bearing table grape cultivar that keeps well in storage. It is a hybrid of Thompson Seedless, Cardinal, and several other Vitis vinifera cultivars. It produces large clusters of medium-large red grapes with a sweet flavor.
Flame Seedless requires a long growing season. As such, the plants fare poorly in cool, damp zones. However, its good qualities, especially seedlessness, sweetness, and long shelf life, make it one of the most heavily farmed table grapes.[citation needed]
The Flame Seedless was brought to the United States by John J. Kovacevich of Arvin, California in 1973. It is the second-most popular grape in the United States. For a Flame Seedless to be called good-quality, it must be plump, well-colored, and firmly attached to the stem. The grapes are usually picked ripe, as they do not ripen after harvest.[2]
