The Valencia Orange is an evergreen tree that flowers year-round in favorable climates or in well-regulated indoor production. The fruit of the Valencia Orange is a hesperidium, a kind of modified berry, in which the outer ovary of the fruit becomes a thin, tough, but spongy peel and the inner ovary forms sections filled with juice and a few seeds. In highly favorable growing conditions, a Valencia Orange tree can grow to as much as 30 to 33 ft. (9 to 10 meters) tall and 25 to 30 ft. (8 to 9 meters) wide. Very old trees that have never experienced winter cold can grow as tall as 50 ft. (15 meters). Each Valencia Orange tree bears hundreds of fruit under ideal growing conditions. Even home growers sometimes get more oranges than they know what to do with. Valencia Orange trees are best adapted to constant temperatures between 59° and 74° F (around 20° C) day and night in their growing season, never experiencing temperatures below 50° F (about 10° C). Even major orange-producing areas in North and South America don't have those conditions, although a few locations along the Mediterranean Sea come close. Valencia Orange trees are self-fertile. They do not need to be pollinated by bees, and you can get oranges from a single tree.
