Description

edit

It is a twining vine-like plant that grows over other shrubs.[1]

Its narrow, arrowhead shaped leaves are opposite and 2.5 to 3.8 centimeters (1 to 1+12 inches) long.[1]

The flowers are pink to purplish, and are produced in umbrella-like heads (umbels) up to 10 cm (4 in) wide.[1][2]

It has a fruit that is 7.5 to 10 cm (3 to 4 in) long, with tufted seeds about 3.5 cm (1+12 in) long.[1]

Distribution and habitat

edit

It can be found from Southern California to Utah, Oklahoma and Texas.[2] It grows at the edge of desert dry washes in the eastern Mojave Desert and Sonoran Desert at altitudes below 610 meters (2,000 feet).[1]

In urban areas the vine freely climbs on plants, trees, as well as having a preference for chain-link fencing in neglected areas.
