Fraxinus oxycarpa, commonly known as Desert Ash or Raywood Ash, is a deciduous tree native to dry, open woodlands and scrub areas in the Mediterranean, the Balkans, and the Caucasus. It typically grows to a height of 40-50 feet (12-15 meters) and a width of 20-30 feet (6-9 meters). The tree has a rounded to spreading canopy with narrow, lance-shaped leaves that turn an attractive claret red in the fall, adding seasonal interest to landscapes. The small, inconspicuous flowers are followed by winged samaras, commonly known as ash keys.

Desert Ash is valued for its drought tolerance and striking fall color, making it a popular choice for urban planting, street trees, and as a feature in large gardens. It requires full sun to thrive and performs best in well-drained soils, tolerating a range of soil types from sandy to clay. While it is relatively easy to maintain, it can be susceptible to pests such as the emerald ash borer and diseases like ash dieback, which can be significant problems. Gardeners should be aware of these potential issues and consider planting resistant cultivars or alternative species where these problems are prevalent.CC BY-SA 4.0
