Overview of the Source Plant of Polygonum Cuspidatum, Distribution, and Growth Environment

Polygonum cuspidatum (scientific name: Tadehagi triquetrum) is a common perennial herbaceous plant belonging to the legume family. Below is an overview of the source plant, its distribution, and growth environment:

  1. Source Plant:
    Polygonum cuspidatum is a herbaceous plant characterized by its square stems and triangular leaves, hence its name "three-edged." It has small, beautiful flowers with a butterfly shape, typically colored in pale purple or pink. Its pod-shaped fruits contain multiple seeds. The root often contains rich bioactive compounds, widely used in the pharmaceutical and health sectors.
  2. Distribution:
    Originally native to southern China and Southeast Asia, including regions like South China, East China, and Central China, as well as countries like India, Myanmar, Vietnam, and Thailand. It is commonly found in tropical and subtropical areas, thriving in moist environments along field edges, grasslands, hillsides, and stream banks.
  3. Growth Environment:
    Polygonum cuspidatum prefers a relatively relaxed growth environment and is not particularly strict about soil requirements, although it favors fertile, well-drained sandy loam. It is commonly found in low hilly areas below 500 meters in elevation, thriving in sunny, moist settings. In conducive growth conditions, it grows rapidly, forming dense clusters.

Polygonum cuspidatum demonstrates wide adaptability in nature, making it not only an ornamental plant but also valuable for its rich medicinal properties, extensively harvested and utilized.
