Helianthus petiolaris is a North American plant species in the family Asteraceae, commonly known as the prairie sunflower or lesser sunflower. Naturalist and botanist Thomas Nuttall was the first to describe the prairie sunflower in 1821. The word petiolaris in Latin means, “having a petiole”. The species originated in Western United States, but has since expanded east. The prairie sunflower is sometimes considered a weed.
Helianthus debilis is a species of sunflower known by the common names cucumberleaf sunflower, beach sunflower, weak sunflower, and East Coast dune sunflower. It is native to the United States, where it can be found along the Atlantic and Gulf Coasts. It is known elsewhere as an introduced species, such as South Africa, Australia, Taiwan, Slovakia, and Cuba.
Village Creek is a blackwater tributary of the Neches River in Texas, United States. It arises in northwestern Hardin County outside the community of Village Mills. Due to the waterway's isolation and absence of impoundments, it is known to be pristine supporting cypress swamps and hardwood forests, as well as many rare and endangered species. It is 63 miles (101 km) long and average streamflow at the mouth is approximately 1,000 cubic feet per second (28 m3/s). It passes through three conservation areas on the way south, being: the Big Thicket National Preserve - Village Creek Corridor Unit, Roy E. Larsen Sandyland Sanctuary, and Village Creek State Park.
Helianthus anomalus, the western sunflower, is a species of plants in the family Asteraceae, found in the southwestern United States.

It is considered by The Plant List to be a synonym for H. nuttallii. However, The Jepson Manual argues that it is distinct from the species.
