Overview

Choisya ternata, known as Mexican orange, is an elegant shrub from the Rutaceae family. This Mexican shrub is celebrated for its glossy green foliage and intensely fragrant white flowers that appear year-round.

Appearance and Bloom

Choisya ternata grows as a compact, densely foliated shrub reaching 1.5-2.5 m tall. Glossy green foliage is trifoliate and remains ornamental year-round. White, five-petaled flowers grow in clusters and release delightfully sweet fragrance. Bloom occurs in spring with secondary flowering in autumn.

Ideal Location

This shrub thrives in full sun to partial shade. A warm, sheltered spot is preferred. Mexican orange also accepts half-shade but blooms better in sun. Plant in a windshield location for better protection.

Watering

Water regularly during first growing year. Once established, the shrub is reasonably drought tolerant. Supplemental watering during extreme dry periods helps. Preference for non-waterlogged conditions.
