Choosing between the many varieties of citrus trees can be confusing. There seems to be an endless selection of orange trees, grapefruit trees, dwarf lemon bushes and even limetta shrubs. But one of the most unusual and captivating tree species is without a doubt the citron citrus tree.

The leaves are quite often lemon scented and are evergreen in nature. What many gardeners love most about the citron citrus tree are its large white and purple blossoms which display a brightly colored center.

The fruit of the citron tree is oblong and rather unusual in shape compared to other citrus fruits. Though there are some tree varieties which are more common than others almost all citron fruits are covered with a rough rind with a soft, sweet and watery flesh.

Some varieties of citron citrus tree include the fascinating and unique “fingered citron”, the “Corsican” variety which was introduced to the US by explorers in 1891 and etrog, diamante and Bajoura.
