Polygonum fowleri
species of plant
Polygonum fowleri, commonly called Fowler's knotweed or Hudsonian knotweed, is a plant species native to the seashores of the northern part of North America. It has been reported from every Canadian province and territory except Alberta and Saskatchewan, as well as from Maine, Alaska, Washington, Oregon, California, and Saint Pierre and Miquelon. It is usually found in gravelly locations along the seacoast.
Polygonum fowleri is a prostrate to ascending herb, often with zigzagged stems. Inflorescences are in the axils of the leaves, each with up to 10 white or pink flowers.
Subspecies
Two subspecies are recognized, treated by some botanists as distinct species:
Polygonum fowleri subsp. fowleri – shores of Atlantic, Pacific, and Arctic Oceans
Polygonum fowleri subsp.

Why this record matters
“Polygonum fowleri” is worth following because a concise public description often conceals a longer documentary argument. Here, Polygonum, fowleri and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Apr 15, 2026. The linked authority identifier is Q16988319.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
