Appearance
The plant is a "trailing vine" with "singly attached heart shaped leaves" and white bell shaped flowers, which have pink to purple centers.
Habitat
It is rarely cultivated but grows wild in North America appearing along roadsides, in fields and along fence rows. Arising from a deep vertical root, this perennial vine with alternate leaves, entwines itself over other vegetation. It sustains itself over the winter with a tuberous root similar to its better known relative, the Sweet Potato.References:
