Androsace occidentalis is a species of flowering plant in the primrose family known by the common name western rockjasmine. It is native to much of southern Canada and the central United States, where it occurs in open habitat such as prairie, especially in moist areas. This is a diminutive annual herb reaching a maximum height of about 7 centimeters. It grows from a basal rosette of oblong hairy leaves no more than one or two centimeters long. It produces an erect inflorescence which is an umbel atop a thin, naked peduncle. The umbel is composed of 5 to 10 tiny flowers, each on a pedicel up to 3 centimeters long. The flowers have a white or pinkish five-lobed corolla inside a cup of pointed reddish sepals.
