Vauquelinia corymbosa ssp. angustifolia - Syn. Vauquelinia angustifolia (Slimleaf rosewood, Chisos rosewood, Guauyul) is native to the southwest Texas - Trans-Pecos region (Big Bend, Chisos Mountains) and Chihuahuan desert (including N. Mexico), usually found at 3000 to 5000 feet elevations, on rocky soils. An evergreen shrub with clusters of fragrant white flowers appearing in Spring and summer, is mentioned by some to be hardy to 0F. In contrast to other Slimleaf rosewoods/Vauquelinia species, the leaves are sharply toothed.
According to Native Plant Database, fresh seeds germinate if planted in fall, but it is recommended that the seedlings be protected from frost. Suggested times for taking cuttings: mid/late summer. Seeds store well if refrigerated.
Very drought resistant, in cultivation outside its natural range the Chisos Rosewood is prone to fungal leaf spot disease, similar to it's cousin, the rose.
