Sphaeralcea coulteri is a species of flowering plant in the mallow family known by the common name Coulter's globemallow.[1] It is native to the Sonoran Desert, its distribution extending from northern Mexico north into California and Arizona. It is an annual herb, its slender, hairy stems sprawling or growing erect to a maximum height near 1.5 meters. The thin, gray-green leaf blades are wide and short, heart-shaped or triangular in shape, and measure up to about 5 centimeters long. They have a few wide lobes along the edges which may have teeth or smaller lobes. The leafy inflorescence bears clusters of flowers each with five wedge-shaped orange petals around a centimeter long, and yellow anthers.
