Arizona rosewood (Vauquelinia californica)
This evergreen shrub belongs to the rose family (Rosaceae). Native to the Sonoran Desert of the United States and Mexico, it can grow up to 30 feet high and 15 feet wide. It has a moderate to slow growth rate and can be trained as a single or multi-stemmed tree. The flowers are creamy white, clustered at the tips of the branches, and bloom in spring. They attract butterflies and produce tan or reddish-brown seed pods that attract birds. The Arizona rosewood requires needs only occasional watering once established. It prefers full sun or reflected sun exposure and dry, rocky soils. It can tolerate temperatures as low as 10°F and is resistant to most pests and diseases. It is a good choice for xeriscape landscaping, as it can be used as a screen, hedge, windbreak, barrier, or border. It requires little maintenance but can be pruned selectively to shape or thin.
