Citron is a straggly, evergreen shrub or small tree growing up to 4 metres tall. It is considered to be a delicate plant and the most tender of the cultivated Citrus species.The plant yields an edible fruit, though it is very acidic and is more commonly used as a flavouring. It also plays a role in the Jewish Feast of the Tabernacles. The plant is occasionally cultivated in the tropics, subtropics and warm temperate zones. In the tropics, where a few fruits ripen throughout the year, the crop is more suited to home gardens than production in orchards
