Citrus consists mainly of evergreen shrubs and trees, which are often armed with spines. They feature simple, leathery leaves that release a pleasing fragrance, typically borne on winged petioles. The plants produce aromatic flowers that are usually white or have a hint of pink, which are succeeded by sizable, juicy fruits.

Citrus reticulata, commonly known as the Mandarin Group, is a spiny evergreen tree that typically reaches heights of 2 to 3 meters. Its leaves are glossy and ovate, measuring up to 5 centimeters in length. In the spring, the tree produces highly aromatic white flowers that can grow up to 4 centimeters in diameter. These flowers give way to small, slightly flattened, round fruit with a textured skin, which is sweet and has a thin, easily detachable peel. This plant thrives best in a cool or temperate greenhouse or conservatory and should be moved outdoors during the summer for optimal growth.
