PERENNIAL: The weak stems of dwarf morning-glory are sometimes procumbant on the soil, but show little if any twinning. Stems may extend out from a woody crown 10 to 20 cm and with many stems forming a hemispherical plant.

FLOWERS: Sky-blue flowers about the diameter of a dime; the corolla limb is nearly circular in outline with sometimes five paler radiations. Five stamens. Flowering late spring into autumn, depending on rainfall.

LEAVES: Leaves are elliptic to lance-shaped and dark green and considerably hirsute.

RANGE: In the Sonoran Desert in Arizona this plant occurs along the upper elevations along the eastern tier and is distributed eastward into the Chihuahuan Desert. Common near Tucson. It is also present in open habitats at higher elevations such as grasslands and piñon-juniper.

FRUIT: Small, dry, spherical capsules typically with two to four seeds.
