It usually has a thick rind and small sections. Originally, the tree came from [[Southeast Asia]]. Today it is mainly grown in [[Sicily]], [[Morocco]], [[Crete]], and [[Corsica]], as well as [[Puerto Rico]]. The tree can grow to a size of about 3 metres. The fruit can grow to a size of about 25&nbsp;cm in length, and about 4&nbsp;kg in weight. The pulp of the fruit is hardly ever used. The rind is used. It is made into an [[additive]] for cooking. [[Jam]] can also be made from the rind. The rind is also used to make [[vegetable oil]], which is used for [[perfume]]s.<ref>{{cite web | url=https://www.britannica.com/plant/citron | title=Citron &#124; fruit &#124; Britannica }}</ref> Generally, it is eaten preserved or in bakery goods, such as [[fruitcake]]s. (The candied peel rather than the fruit is often used in cooking.) In some cultures, it is made into a fruity [[tea]]. [[Pliny the Elder]] states that in his time <!-- , despite attempts to transport it into the [[Roman Empire]] in tightly-packed pots-->, the citron could only be grown in Media and Persia (''[[Natural History|HN]]'' xii.7). The Romans tried to transport it into the [[Roman Empire]] in tightly packed pots, but failed, according to Pliny. There is evidence, however, which shows it was cultivated in the Mediterranean during Pliny's lifetime. Zohary and Hopf believe this tree was first domesticated in India. They think that its wild forms, along with those of the [[mandarin orange|mandarin]] and [[pomelo]], were the original citrus species.<ref>Daniel Zohary and Maria Hopf, ''Domestication of plants in
