The Flame Seedless was brought to the United States in 1973. It is a vigorous, heavy-bearing table grape cultivar that produces sweet, large clusters of medium-large red grapes. Besides, its sweetness and long shelf life make it one of the most heavily farmed table grapes and the second-most popular grape in the United States. As a matter of fact, the vitamin K in all grapes supports healthy bones and tissues; while the antioxidant vitamin C in these gorgeous fruits promotes healing and helps your body to absorb iron.
