Choisya ternata, commonly known as Mexican Orange Blossom, is an evergreen shrub that is prized for its aromatic, glossy dark green leaves and fragrant white flowers. This versatile shrub can grow between 4-6 feet tall and wide, with a dense, rounded habit. In spring, it produces clusters of star-shaped white flowers that fill the air with a citrus-like fragrance, which is why it’s often planted near walkways or patios to enjoy the scent. The leaves are aromatic as well, releasing a mild orange fragrance when crushed. This plant is drought-tolerant once established and thrives in full sun to partial shade. Its year-round interest, fragrance, and easy maintenance make it a popular choice for gardens, whether in shrub borders, as a hedge, or as a specimen plant.
Choisya ternata
- Light: Prefers full sun but can tolerate partial shade, though flowering may be reduced in deeper shade. Full sun encourages the best growth and flower production.
- Watering: Water regularly, especially during dry periods, but allow the soil to dry out slightly between waterings. Once established, it is relatively drought-tolerant.
- Soil: Thrives in well-draining, moderately fertile soil. It prefers slightly acidic to neutral pH but can adapt to a variety of soil types, including sandy or clay soils.
- Temperature: Hardy in USDA zones 7-10. It can tolerate mild frost, but heavy winter frost may damage the plant. Ideal for temperate climates.
- Humidity: Grows well in average humidity but benefits from good air circulation to prevent fungal issues.
- Fertilizer: Use a balanced, slow-release fertilizer in early spring to encourage healthy growth and abundant flowers. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
- Pruning: Prune lightly after flowering to maintain shape and size. Removing dead or damaged wood can help promote new growth. Avoid heavy pruning, as this may reduce flowering.
- Propagation: Easily propagated by softwood cuttings taken in late spring or early summer. Rooting hormone may help encourage faster rooting.
- Pests/Diseases: Generally pest-resistant, though it may occasionally attract aphids or whiteflies. Watch for fungal diseases in humid or overly wet conditions.
- Landscape Use: Ideal for shrub borders, hedges, or as a specimen plant in gardens. Its fragrant flowers and evergreen foliage make it perfect for adding year-round interest to patios, walkways, or cottage gardens.
