[Illustration: Evolvulus arizonicus]
Common name: WILD-MORNINGGLORY
Arizona desert: (_Evolvulus arizonicus_). Sky blue. April-October.
Texas desert: (_Evolvulus alsinoides_). Azure blue. April-September.
Convolvulus family. Size: Spreading perennial herbs up to 2 feet.
Although _E. arizonicus_ is considered one of the desert’s most
beautiful wildflowers, members of the genus are by no means limited to
the desert. They are found in sunny locations on desert grasslands, open
plains and dry mesas below 5,000 feet from the Dakotas and Montana to
Argentina.
The flowers, although rarely more than ½ inch in diameter, are bright
azure or sky blue, and seem large in comparison with the small leaves
and weak, spreading stems of the plant that bears them.
Although the genus _Ipomoea_ is the true Morningglory, blossoms of
_Evolvus_ are similar in appearance, although flattened, hence are
sometimes called Wild-morningglory.
