Citrus ichangensis x Citrus reticulata. Yuzu trees, upright up to about 10', are the only citrus trees that can survive temperatures down to about 20 degrees. A necessary ingredient in many Asian dishes, the Yuzu fruit won't win any beauty contests, but its flavor and fragrance have no peer. Yuzu juice is used to make ponzu, the deeply fragrant rind is grated onto many dishes, and the fruit is plopped into a hot bath during the winter solstice. Fruit ripens during the fall/winter and watch out for vicious thorns while harvesting. As of March 2016, trees are about 2' above pot, 1/2" caliper trunk, smaller than photo, no fruit or flowers. Grown on dwarfing rootstock in 5 gal containers. Shipped in 3' x 1' x 1' braced box. OUT OF STOCK UNTIL LATE SUMMER 2016.
