Larrea is a genus of flowering plants in the family Zygophyllaceae, commonly known as the creosote bush. It is native to arid regions of North America, particularly in the southwestern United States and northern Mexico. The plant is well-adapted to dry environments, featuring small, waxy leaves that help reduce water loss. The most well-known species is Larrea tridentata, which can grow up to 10 feet tall and is recognized for its distinctive smell, reminiscent of creosote. This plant plays a crucial role in its ecosystem, providing habitat and food for various wildlife while also helping to stabilize soil in desert areas.
