Evolvulus arizonicus

Evolvulus arizonicus A. Gray

Wild Dwarf Morning-glory, Arizona Blue-eyes

Convolvulaceae (Morning-Glory Family)

Synonym(s): Evolvulus arizonicus var. laetus, Evolvulus laetus

USDA Symbol: EVAR

USDA Native Status: L48 (N)

A plant with grayish hairs, slender erect stems, and 1 shallow, bowl-shaped, blue to purplish-blue flower on a slender stalk in each upper leaf axil.

In the arid parts of the Southwest, truly blue flowers are uncommon; this flower, often as blue as those of true flax (Linum), is the prettiest of its genus in the whole region. It is very similar to E. alsinoides, a closely related species called Ojo de Vibora (Spanish for "eye of the viper"), which has corollas 1/8-3/8" (4-8 mm) wide; it is common from Arizona east to Texas and south into Mexico. Other Evolvulus in the West have very short stalks beneath the flowers and paler corollas.
