Description: The morning-glory-like flowers are funnel-shaped, up to 1/2 inch (1.3 cm) wide, and have a large, white, 5-pointed star in the center and a very short flower stalk. The flowers close in the evening and remain closed on cloudy days. The flowers are followed by hairless, egg-shaped seed capsules. The leaves are alternate, grayish green in color, densely hairy above and below, and linear-oblong, narrowly oblanceolate, or narrowly lanceolate in shape. The stems are green, hairy, and woody near the base of the plant. The plants are wider than they are tall.
The similar Slender Dwarf Morning-glory (Evolvulus alsinoides) has longer flower stalks that typically equal the leaves in length, while Wild Dwarf Morning-glory (Evolvulus arizonicus) has brighter blue flowers with a small, distinct, white center, and Silver Dwarf Morning-glory (Evolvulus sericeus) has silver-edged leaves.
