Citrus aurantifolia

Description: C. aurantifolia is a shrubby tree, to 5 m (16 ft), with many thorns. Dwarf varieties exist that can be grown indoors during winter months and in colder climates. Its trunk, which rarely grows straight, has many branches, and they often originate quite far down on the trunk. The leaves are ovate, 25–90 mm long, resembling orange leaves (the scientific name aurantifolia refers to this resemblance to the leaves of the orange, Citrus aurantium). The flowers are 25 mm in diameter, are yellowish white with a light purple tinge on the margins.

Flowering and Fruiting: October to December.

Economic Importance: Obtain food products such as dehydrated citrus products or marmalades, jams, sorbet, pickles, jellies, candies and sugar boiled. Citrus essential oils are another by-product of citrus fruits. Essential oils are volatile oils obtained from the citrus fruit peels’ sacks.
