aurantiifolia is a shrubby tree, to 5 m (16 ft), with many thorns. Dwarf varieties exist which can be grown indoors during winter months and in colder climates. Its trunk rarely grows straight, with many branches, often originating quite far down on the trunk. The leaves are ovate, 2.5–9 cm (1–3.5 in) long, resembling orange leaves (the scientific name aurantiifolia refers to this resemblance to the leaves of the orange, C. aurantium). The flowers are 2.5 cm (1 in) in diameter, are yellowish white with a light purple tinge on the margins. Flowers and fruit appear throughout the year, but are most abundant from May to September in the Northern Hemisphere.
