Koenigia phytolaccifolia (synonym Aconogonon phytolaccifolium) is a species of flowering plant in the knotweed family, [1] known by the common name poke knotweed.
Koenigia phytolaccifolia is a perennial herb up to 200 cm (79 in) tall. The lance-shaped or pointed oval leaves are 10 to 20 centimeters long and borne on petioles. The leaves have large stipules which form reddish ochrea up to 3 centimetres (1.2 inches) long. The inflorescence is a long array of branching cluster of many white or greenish flowers. Each flower is about 4 millimetres (0.16 inches) wide and has tiny protruding stamens tipped with yellow or pink anthers. [2]
Koenigia phytolaccifolia is native to the western United States: California, Oregon, Washington, Nevada, Idaho, and Montana. [3] [4] [5]
Persicaria is a genus of herbaceous flowering plants in the knotweed family, Polygonaceae. Plants of the genus are known commonly as knotweeds or smartweeds. It has a cosmopolitan distribution, with species occurring nearly worldwide. The genus was segregated from Polygonum.
Polygonum is a genus of about 130 species of flowering plant in the buckwheat and knotweed family Polygonaceae. Common names include knotweed and knotgrass. In the Middle English glossary of herbs Alphita, it was known as ars-smerte. There have been various opinions about how broadly the genus should be defined. For example, buckwheat has sometimes been included in the genus as Polygonum fagopyrum. Former genera such as Polygonella have been subsumed into Polygonum; other genera have been split off.
