Field Bindweed
Convolvulus arvensis
Photographed in Rackensack Canyon, Maricopa Co., Arizona. Aug. 3, 2008. Notice that a Green Sweat Bee (Agapostemon texanus) is exiting a flower.
VINE-ANNUAL: An annual vine that clambers and twines upon taller plants.
FLOWERS: White or pink broadly funnel-form flowers are attractive and
have encouraged their propagation by well-meaning gardeners. In many states
this plant is classified as a noxious weed making transport and propagation
illegal. Blooms May thru Oct. depending on available moisture.
LEAVES: Leaves are arrow-shaped and may have more-or-less well defined
hastate lobes.
RANGE: In the Sonoran Desert in Arizona and Mexico this non-native is
most likely found within agricultural fields or gardens. But it is also
adventive/invasive in riparian and chaparral habitats at the higher elevations
of the Sonoran Desert. Otherwise this plant is widely distributed across the
northern hemisphere where it is a economically troublesome weed.
FRUIT: Dry, spherical capsules typically with four seeds.
