Climbing Bindweed

Climbing Bindweed, Calystegia sepium or related Convolvulus species in the family Convolvulaceae, is a vigorous twining perennial vine native to temperate regions of Europe, Asia, and North America, widely naturalized in disturbed habitats worldwide. The species climbs over hedgerows, fences, tall herbs, and shrubs by twining its flexible stems counterclockwise around supporting structures, sometimes smothering vegetation under dense leafy growth. The leaves are broadly arrow-shaped or hastate, and the funnel-shaped flowers are large, white to pale pink, and open during daylight hours. Like its relatives, Climbing Bindweed has deeply buried, extensively spreading rhizomes that are extremely difficult to eradicate once established. The extensive root system enables survival of herbicide treatments and mechanical disturbance, making the species a persistent weed in gardens, agricultural land, and riparian habitats. Despite its weedy character, the flowers provide nectar for bumblebees and are visited by hawk moths at dusk. The species is not threatened globally; it is considered common and often invasive across temperate regions. It has considerable cultural significance, appearing frequently in art and folklore as a symbol of persistence and entanglement.

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.
