Choisya dumosa var. dumosa

Desert mock orange is a compact, fragrant evergreen shrub native to the Chihuahuan Desert region, making it well adapted to hot, dry conditions in partial shade or full sun. Plant in well-drained soil and water deeply but infrequently once established; it is fairly drought tolerant when mature. Its white, citrus-scented flowers attract pollinators and make it a lovely low-maintenance addition to xeriscape or native plant gardens.
