Description
Texas Olive (*Cordia boissieri*), also known as Anacahuita or Mexican Olive, is an evergreen to semi-deciduous shrub or small tree native to southern Texas and northeastern Mexico. It typically reaches heights of 15 to 20 feet (4.5 to 6 meters) with a spread of 10 to 15 feet (3 to 4.5 meters), forming a symmetrical, rounded crown. The tree features large, leathery, ovate leaves measuring 9 to 18 centimeters (3.5 to 7 inches) in length and 5 to 9 centimeters (2 to 3.5 inches) in width, with a velvety texture and silvery undersides. From spring to fall, it produces clusters of showy, trumpet-shaped white flowers with yellow throats, each about 3 to 5 centimeters (1.2 to 2 inches) across, attracting various pollinators. These blooms are followed by olive-like, yellow-green drupes approximately 1.2 to 2.4 centimeters (0.5 to 1 inch) long, which are sweet but mildly toxic when consumed in large quantities.
✂️🫘 **Methods to Propagate:**
Texas Olive can be propagated by seeds, semi-hardwood cuttings, softwood cuttings, or air layering. Seeds should be collected from mature fruits, cleaned, and sown in well-draining soil. Semi-hardwood or softwood cuttings can be treated with rooting hormone and placed in a suitable growing medium. Air layering involves inducing roots on a stem while still attached to the parent plant before severing and transplanting.
🌞💧 **Sun and Water Requirements:**
This species thrives in full sun, requiring at least 6 to 8 hours of direct sunlight daily for optimal growth and flowering. It prefers well-drained soils and is highly drought-tolerant once established, making it suitable for xeriscaping. Regular watering is beneficial during the establishment phase, but mature plants can withstand extended dry periods.
🧑🌾👩🌾 **When to Harvest:**
While the fruits are not commonly consumed due to their mildly intoxicating effects when eaten in large quantities, they can be harvested when they turn yellow-green and are fully ripe. Caution is advised if considering consumption, and it's essential to ensure they are prepared safely.
Purpose
- **Ornamental:** Texas Olive is prized for its attractive flowers and foliage, making it a popular choice in landscaping for aesthetic enhancement.
- **Wildlife Attractor:** The flowers provide nectar for pollinators such as bees, butterflies, and hummingbirds, while the fruits serve as a food source for birds and small mammals.
- **Erosion Control:** Its deep root system stabilizes soil, making it effective in preventing erosion, particularly in arid and semi-arid regions.
