Pink Smartweed (Persicaria bicornis), Polygonaceae Family, Texas native, annual, blooms June through October, is considered to be a noxious weed by many

Pink Smartweed (Persicaria bicornis) is a native wetlands plant that inhabits moist disturbed places, marshes, edges of ponds, rivers and reservoirs, ditches and moist cultivated fields. Many times it is included in Persicaria pensylvanica. However, it can be distinguished easily by its heterostylous flowers. Its exserted stamens and styles give it a more fringed appearance. The blooms are more "open"; whereas, the Persicaria pensylvanica blooms are more cupped. Also, its fruit (achenes) usually have an obscure or prominent hump in the center of one face. which typically ruptures the side of the perianth upon fruiting. In addition, the Persicaria bicornis leaf blades are narrower than the leaf blades of Persicaria pensylvanica.
