Choisya–commonly called Mexican Mock Orange –is an evergreen subtropical shrub cultivated both for its attractive foliage and long-lasting clusters of white flowers. The fragrant star-shaped flowers resemble orange blossoms.
Choisya is fast growing to about 8 feet (2.5m) tall and wide. Choisya can be planted as an informal hedge or massed as a screen. It can also be trained against a wall.
Choisya’s clusters of white flowers stand out against the plant’s bright green foliage. Where summers are hot Choisya should be planted in filtered sun.
Choisya is a genus of eight or nine species of these evergreen shrubs. Choisya is native to canyons and rocky slopes in the southwest United States and Mexico. Only one species, Choisya ternata, called Mexican orange, is commonly cultivated in gardens.
