Summary

Choisya dumosa, commonly known as Mexican Orange or Mexican Starleaf, is an evergreen shrub native to the semi-arid regions of the Southwestern USA and Northern Mexico, particularly found in chaparral and scrub habitats. It typically grows to a height of 1-5 feet (0.3-1.5 meters) and a width of 2-6 feet (0.6-1.8 meters). The plant has a compact and rounded form, with aromatic, compound leaves that give it a fine-textured appearance. In spring, clusters of fragrant, star-shaped white flowers bloom, adding to its ornamental value. The flowers are moderately showy and attract pollinators.

Mexican Orange is valued for its drought tolerance and its ability to thrive in part shade, making it suitable for xeriscaping and as an understory plant in water-conserving gardens. It is also used in border planting and as an informal hedge. This shrub prefers well-drained soils and requires minimal water once established. It is generally free from serious pests and diseases but can be affected by root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
