Mesquite

Mesquite serves as an excellent xeriscape specimen tree providing filtered shade, sculptural twisted trunk forms, and seasonal interest with fragrant yellow catkin flowers. Its thorny branches create effective barrier hedges while the deep taproot (up to 160 feet) makes it ideal for erosion control and windbreaks in arid landscapes.

Traditional medicine uses mesquite gum as a treatment for wounds, sore throats, and digestive issues. The leaves and bark contain antibacterial compounds and have been used to treat eye infections, while the sap serves as a natural adhesive bandage. Tea from the pods helps regulate blood sugar levels.

Mesquite pods yield a sweet, nutty flour high in protein (11-17%), lysine, calcium, and fiber. The flour adds caramel-like sweetness to baked goods and can replace 25% of wheat flour in recipes. Fresh pods can be chewed for their sweet pulp, while dried pods make a coffee substitute when roasted and ground.

As a nitrogen-fixing legume, mesquite enriches soil while providing food and shelter for over 60 species of birds and mammals. The flowers support native bees and produce distinctive honey. Deep roots mine minerals from subsoil, creating nutrient-rich leaf litter that builds desert topsoil.

Deciduous shrub or tree reaching 30 feet with distinctive bipinnately compound leaves, paired thorns at nodes, and twisted, dark bark. Fragrant yellow-green catkin flowers appear in spring, followed by 4-8 inch tan seed pods. Multiple species exist, with honey mesquite (Prosopis glandulosa) most common in southwestern US.

Mesquite wood is extremely hard (2345 Janka rating), dimensionally stable, and naturally rot-resistant. The beautiful reddish heartwood with dark streaks is prized for high-end furniture, flooring, and turning. Historic uses include fence posts lasting 50+ years and railroad ties. Premium BBQ smoking wood.

Some mesquite trees are over 1000 years old. During droughts, they can reverse photosynthesis at night, releasing oxygen and absorbing CO2. The wood is so dense it doesn't float. Native Americans used every part: pods for food, wood for tools, roots for rope, and even made a type of candy from the sap.
