Evolvulus is a genus of flowering plants in the Convolvulaceae, the morning glory family. They are known generally as dwarf morning glories. Most are native to the Americas. There are about 100 species.

Description

These plants are annual and perennial herbs and shrubs. They have non-twining stems. The leaves have smooth edges. Flowers are borne singly or in small clusters, or sometimes in spikes. The corolla is round and flat or bell-shaped. The fruit is a capsule containing 1 to 4 seeds.

Taxonomy

Etymology

The genus name Evolvulus comes from the Latin word meaning "to unroll", inspired by its non-vining form.
