EPA Level I Region
North American Deserts spans the dry interior west, from the Columbia Plateau and Snake River Plain down through the Great Basin to the Mojave, Sonoran, and Chihuahuan deserts. Rainfall is scarce throughout, but the timing differs sharply: winter rain in the north and west, a summer monsoon in the southeast. Desert natives such as penstemon, brittlebush, and apache plume are among the only plants that hold their shape here without irrigation, which is why so many water districts in this region pay homeowners to plant them.
Ecoregions inside it: 10. Native range is set at that finer level, so start there rather than here.
Pick the one that covers your yard. Each has its own plant list, conditions, and maintenance notes.
These ecoregions do not have their own page yet. The full plant library covers them in the meantime.
Pollinator Patch resolves your ZIP to its ecoregion and builds a front-yard plan tuned to the soil, climate, and HOA expectations where you actually live.
