About

Citrus x microcarpa is a dense evergreen shrub that can grow up to 4 meters in height. It features glossy, elliptical leaves that are a deep green. The plant produces small, aromatic white flowers, which give way to round orange fruits measuring 3 to 4 centimeters in diameter. While the skin of the fruit is sweet and edible, the interior is quite sour and acidic.
