Persian lime trees are best known for their dense, glossy evergreen foliage, and small buds that produce pure white, fragrant blossoms. Persian limes are those most often found in grocery stores. Abundant, large limes grow at the ends of the branches of the trees and need little heat to ripen. The thin, smooth green rind and seedless, juicy flesh make it ideal for cooking, zesting and garnishing. It produces abundant fruit when grown both indoors and outdoors.
