Ipomoea ternifolia is a desert ephemeral native to Arizona and Mexico. Desert ephemerals are annuals that are adapted to brief periods of heavy rains and they are remarkable for the speed with which they flower and set seeds.

Description

• Ipomoea ternifolia is a climbing or twining plant in the morning-glory family (Convolvulaceae). The species name ternifolia refers to leaves arranged in groups of three, a characteristic reflected in its foliage. Like other morning glories, it produces funnel-shaped flowers and capsule-like fruits containing seeds. Its growth form, leaf shape, and flower colour can vary with the variety or subspecies, so identification is best confirmed using the leaves, flowers, and mature fruit together.

Range

• Ipomoea ternifolia is native to the southwestern United States, including Arizona, Mexico, and parts of Central America, including El Salvador and Costa Rica. In Mexico, it occurs across numerous states, including Guerrero. It is native to Zihuatanejo, Guerrero, and the surrounding area.

Habitat

• This species typically grows in warm, seasonally dry tropical environments, including tropical deciduous forest, scrub, grassland margins, roadsides, and disturbed ground. It is found from low elevations to upland areas and commonly flowers during the rainy season and into the dry season.
