Cynanchum caudatum

Cynanchum caudatum, commonly known as the Japanese milkweed or Kuril milkweed, is a perennial plant native to Japan, the Kuril Islands, and Sakhalin. It has also naturalized in parts of South America including northeastern Argentina, southeastern Brazil, and Paraguay. This plant thrives in moist environments with light to partial sun exposure and can grow in various soil types, from sandy to clay-rich soils. Its edible roots make it a valuable resource for those interested in foraging or traditional uses. One distinctive feature is its ability to adapt to diverse climates and habitats across its native range and beyond.
