About Persicaria bicornis (Raf.) Nieuwl.
Persicaria bicornis (Raf.) Nieuwl. is an annual herb that can reach up to 180 cm (5.9 ft) in height. It produces lanceolate leaves that grow up to 18 cm (7 in) long, and clusters of small pink flowers. Each flower has 5 pink tepals, 6 to 8 stamens with pink or red anthers, and one compound pistil with 2 to 3 styles emerging from the base of the flower. Blooms have a fringed appearance, and the heterostylous flowers are positioned very close together. This species can be distinguished from Persicaria pensylvanica by its narrower leaf blades.
Persicaria bicornis is native to North America, where it has been recorded in Arkansas, Colorado, Illinois, Louisiana, Missouri, and Texas, among other locations. It grows in disturbed sites including moist ditches, and along the shorelines of ponds and reservoirs. Its growing season typically runs from June to October. There are no known human uses for Persicaria bicornis.
