Calystegia hederacea is a perennial vine
commonly found in grasslands or roadsides,
propagating itself by extending its white
underground stems, the vine growing and winding
itself around something else. The alternate leaves
are hastate, 3-7cm long, the basal parts overhanging
sideways, looking like a pair of ears. Flowers
singly come on 2-5cm stalks born on leaf axils.
Bloom time: June-August.
