The Calamondin comes from China. It became widespread in the Philippines and in Indonesia, and was imported to Italy only in 1950s.

It is a rather vigorous tree, with a rounded and dense growth habit and small, oval leaves. According to many botanists, it is likely a hybrid between the Kumuqat and the Mandarin Orange.

Its flowers are white and small, and they have a delicate, intense perfume. It can bloom from Spring to late Autumn. Its fruits are small and round, they have a sweet, thin, intense-orange peel and a sour pulp with few seeds.
