Larrea tridentata

Gobernadora (Larrea tridentata) is a perennial shrub very characteristic of the deserts of North America. It has small and very rough dark green leaves, producing secondary metabolites rich in phenols and flavonoids that it uses to repel herbivores and pests (there are no known pests that affect this plant). It produces a resin that prevents plants from growing around it and competing for scarcity of water and nutrients in the desert.
During the summer, it grows small, yellow hermaphroditic flower.
Research is currently being carried out on its secondary metabolites to use them to control pests in agriculture and diseases in humans.
