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.
