The orange is a hybrid of ancient cultivated origin, possibly between pomelo (Citrus maxima) and mandarin (Citrus reticulata). It is an evergreen flowering tree generally growing to 9 to 10 m in height (although very old speciments have reached 15 m). The leaves are arranged alternately, are ovate in shape with crenulate margins and are 4 to 10 cm long. The orange fruit is a hesperidium, a type of berry. Oranges can be grown outdoors in warmer climates, and indoors in cooler climates. Like most citrus plants, oranges will not do well unless kept between 15.5 degrees celsius to minus 29 degrees celsius (60 degrees fahrenheit to minus 85 degrees fahrenheit). Orange trees grown from the seeds of a store-bought fruit may not produce fruit, and any fruit that is produced may be different than the parent fruit, due to modern techniques of hybridization.
