Vauquelinia californica (Arizona Rosewood) A moderately slow-growing upright low branched evergreen shrub or small tree to 10 to 25 feet tall but easily maintained at 8 to 10 feet tall. It has dark green, leathery, lance-shaped 4 inch long by 1 inch wide leaves that have serrated margins and in late spring appear the tiny white flowers in dense flat clusters, followed by tan fruit that long remains on the plant and can be pruned off (or not). Plant in full sun in a well-drained soil and irrigate infrequently to not at all, though its growth rate and ultimate size can be enhanced by supplemental irrigation and then an infrequent and deep watering is best. Hardy to 10 to 15 F and useful in USDA Zones 8-10. It required little to no maintenance but branches can be pruned lightly to shape, but does not take to shearing. This plant is often compared to looking a bit like oleander and is similarly useful as a large screen. Arizona Rosewood was grows naturally at elevations from 2500 to 5000 feet in the Madrean (Sierra Madre Occidentale) Sky Islands habitats of Southern Arizona, New Mexico and Northwestern Mexico (Sonora) as well as in the Peninsular Ranges in Baja California and northern Baja California Sur. The genus was named after the French chemist and botanist Louis Nicolas Vauquelin and though the specific epithet has many believing this plant native to the state of California, it is not native within the boundaries of the state of California and this name likley came about because it was first described from plants found near the California and Arizona border and there were isolated occurrences in Baja California in Mexico.  The information on this page is based on research conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens that we have observed it in. We also will incorporate comments received from others and always appreciate getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that might aid others in growing Vauquelinia californica.
