Aloysia wrightii is a species of flowering plant in the verbena family known by the common names Wright's beebrush and oreganillo. It is native to the Sonoran Desert of southwestern [United States] and northern Mexico, where it can be found in moist desert canyons, scrub, and woodland habitat. This is a thickly branching shrub which reaches nearly two meters in maximum height and is generally rounded in form. It has small, oval-shaped to nearly round leaves each no more than two centimeters long. The leaves have lightly toothed edges and hairy undersides. The inflorescence is a narrow, woolly spike up to 6 centimeters long, with small, widely spaced white flowers. It is a valuable nectar source for native solitary bees.
