Mesquite is a type of hardy tree or shrub native to the Southwest, known for thriving in hot, dry climates. It’s “everywhere” in that region because it’s incredibly drought-resistant and its deep roots help it survive where other plants can’t. Mesquite wood is also popular for grilling thanks to its rich, smoky flavor. While it has ecological benefits—like preventing erosion and fixing nitrogen in the soil—it can also be invasive if not managed. Its widespread presence is a reminder of how native plants adapt to harsh environments.
