- Comments
- The species is recognized by its saccate, overlapping, obtuse bracteoles. The subsp. differs from European ssp. silvatica by its characteristicly square leaf sinus and tendency to produce a pair of flowers at each leaf axil. This taxon has been widely lumped into a broad concept of Calystegia sepium, and most Virginia specimens have still not been segregated from other taxa of the C. sepium complex. The current map is therefore very incomplete. However, confirmed records indicate that it is widely distributed in Virginia, and very common in some areas.
- Habitat
- Open alluvial habitats, field edges, roadsides, weedy clearings, and waste ground more or less statewide.
- Native Status
- Native
