The Mexican Lime tree is medium in size, spreading and bushy with numerous willowy, fine-stemmed branches. Its foliage is dense and consists of small, pale green, blunt-pointed leaves. The trees are somewhat ever-bearing but their main crop comes in the winter (or earlier in very hot climates). Mexican lime trees are sensitive to cold. Flowering occurs throughout the year but mainly in the spring and late summer. The blossoms are pure white and fragrant.
