[1] Koenigia polystachya is native to Asia (southwestern China, Indian Subcontinent, Myanmar, Afghanistan) and it is planted many places as an ornamental.

It has the capacity to become an invasive species and has established itself in some parts of North America, primarily the Pacific Coast of the United States and Canada.

[5] Koenigia polystachya is a rhizomatous perennial herb producing thick, hollow, erect stems easily exceeding one meter (40 inches) in length.

It may also spread asexually if sections of the stem containing rooting nodes are separated and moved to a new area; chopping the plant into small pieces does not necessarily keep it from growing.

[4] Called thothnay in Sikkim and Darjeeling areas of India, the pleasantly sour-tasting edible shoots and stems are used as vegetable or used to make piquant condiments and accompaniments for meals.
