The Jupiter grape, created by American breeders at the University of Arkansas, is an excellent bunch producer of reddish-blue, seedless grapes. The flavor is said to be that of Muscat. The fruit will turn completely blue as it fully ripens in August-September. It ripens well even in a cool maritime summer and may ripen sooner where summers are warmer. Plant in full sun in a place that will provide shade, cover a wall, trellis or arch and will become a beautiful focal point in your garden.
