Creosote Bush (Larrea tridentata) Blossoms in Sabino Canyon, November 10, 2014 — Images by kenne
One of the most common plants in Sabino Canyon is the creosote bush. Our neighbors south of the border cal the plant “gobernadora,” Spanish for “governess,” because of its ability to secure more water by inhibiting the growth of nearby plants. The plant exhibits a characteristic odor of creosote, and is the small inhabitants of the desert small after rain — the “smell of rain”. The bush normally blooms in the spring and summer, so the these new blossoms are a pleasant addition to the fall flowers in the Sonoran desert. Unlike most desert plants, the creosote bush has no thorns for defense, instead it is provided by a suite of toxic/ anti-feeding chemicals including the phenolic compound nordihydroguaiaretic acid.
