Climbing False Buckwheat

Climbing False Buckwheat, Fallopia scandens (also known as Polygonum scandens), is a vigorous annual or short-lived perennial vine in the family Polygonaceae native to eastern North America, occurring from the Great Plains east to the Atlantic coast and from southern Canada south through the eastern United States to Mexico. It climbs over shrubs, fences, and tall herbs by twining its stems, reaching several meters in length. The leaves are broadly heart-shaped, and the small, greenish-white flowers are borne in elongated, drooping racemes in summer and autumn. The triangular achene fruits are enclosed by winged, pinkish-white tepals that facilitate wind and water dispersal. Climbing False Buckwheat grows in moist, disturbed habitats including stream banks, woodland margins, thickets, roadsides, and fencerows, tolerating a wide range of soil conditions. It is closely related to the invasive Japanese Knotweed (Fallopia japonica) but is less aggressive and is considered native in eastern North America. The seeds are eaten by many birds and small mammals. The species is not threatened and is a common component of disturbed vegetation across its extensive native range.

coast amaranth

Coast amaranth (Amaranthus pumilus) is an annual herb in the family Amaranthaceae, native to the Atlantic and Gulf coasts of the eastern United States, where it once grew on coastal foredunes, beach strand, and shell-hash substrates above the high tide line from New York south to South Carolina. It is a low-growing, fleshy plant with small, rounded leaves and inconspicuous green flowers typical of the genus. Coast amaranth is assessed as Extinct in the Wild by the IUCN, as it has not been reliably documented from wild populations since the mid-20th century; the last confirmed collections date to the 1960s. The species' decline and likely extinction resulted from intense human pressure on Atlantic coastal habitats through shoreline development, beach stabilisation, vehicular traffic on beaches, and increased storm frequency disrupting pioneer dune vegetation. It is federally listed as Threatened in the United States, though this listing predates confirmed extinction in the wild. A small number of ex-situ accessions may exist in botanical garden collections. Genetic material and seed banking efforts represent the only remaining conservation options for this critically reduced species.
