Calystegia sepium - (image 1 of 5)

 

Taxonomy

Family: Convolvulaceae

Habitat

Best known as a plant of ruderal areas like pastures, thickets, weed lots. It also occurs in calcareous meadows and prairies, where it's weedy nature is far less apparent. I often find it growing on chain-link fence.

Associates

Varies depending on habitat.

Distribution

 

Widespread in North America and Eurasia. Our plants include native and introduced forms.

Morphology

Twining vine to 3 m, occasionally trailing. Leaves with a triangular to oblong silhouette, hastate or sagittate, 5-10 cm, on long petioles. Flowers solitary on peduncles 5-15 cm, with two large bracts inserted just beneath the calyx; bracts ovate or oblong, 1-2 cm, often cordate at the base, mostly covering the calyx; corolla pink or white, 4-7 cm, resembling that of a morning glory.

Notes

Flowers early June to late September

Wetland indicator: Facultative

Considered to be a weed in some states. Often confused with the smaller and far more weedy Convolvulus arvensis; introduced from Europe with smaller bracts that are far removed from the calyx.
