Large citrus tree that needs warm conditions and ample space. Produces heavy crops of tart-sweet fruit that hang on the tree for months (natural storage). Needs more heat than most citrus to develop sweetness. Fruit from cool climates is excessively sour. One of the larger citrus species; a mature tree reaches 6-8m. Grafted trees on trifoliata or Swingle citrumelo rootstock. Self-fertile but benefits from warm conditions during flowering for good fruit set.
