Description
C. gronovii is a dioecious perennial that grows as a forb/herb or vine.[2] Scales can produce up to five axillary branches, which can then become their own plant after contacting a host.[3]
Distribution
This species is found in all of the lower 48 United States except for Washington, California, Nevada, and Utah. It is also found in Canada from Alberta eastward to Quebec, New Brunswick, and Nova Scotia.[2]
Ecology
Habitat
This species is found on a wide variety of herbaceous and woody plants within stream banks, bottomland forests, bogs, marshes, swamps, wet fields, and wet disturbed areas.
Phenology
Flowering occurs from late July through November in the southeastern and mid-Atlantic United States.[1]
Seed bank and germination
Seeds germinate in soil, but roots die off as the plant twines around a host and sends out suckers that penetrate the host's tissues and obtain nutrients.[4] Embryogenesis studies reveal no primary root meristem in this species.[3]
