Desert Myrtlecroton: A Hardy Native Shrub for Southwestern Gardens
If you’re looking for a low-maintenance native shrub that can handle the heat and drought of the American Southwest, meet the desert myrtlecroton (Bernardia obovata). This unassuming but resilient perennial shrub might not win any beauty contests, but it’s exactly the kind of steady performer that makes xeriscaping and native gardening a breeze.
What Makes Desert Myrtlecroton Special?
Desert myrtlecroton is a true southwestern native, naturally occurring in New Mexico and Texas. As a multi-stemmed woody shrub, it typically grows to a modest height of 4-5 meters (13-16 feet), though it usually stays much smaller in garden settings. Its oval-shaped leaves and inconspicuous flowers won’t steal the show, but that’s not really the point with this plant—it’s all about reliability and ecological value.
Where You’ll Find It Growing Wild
This hardy shrub calls the southwestern United States home, with natural populations documented in New Mexico and Texas. It’s perfectly adapted to the challenging conditions of this region, including intense sun, low rainfall, and alkaline soils.

- Native plant benefits: Supporting local ecosystems while requiring minimal resources
- Drought tolerance: Once established, it laughs in the face of dry spells
