Duckweed

Duckweed (Lemna minor), a small, free-floating aquatic plant, is native to Afghanistan and has a widespread distribution across North America, Europe, Asia, and Africa. This perennial forb/herb thrives in various habitats, with a hardiness rating of 4-8. Duckweed's light requirement is moderate, making it adaptable to diverse environments. It can be found growing in soils with a pH ranging from 4.1 to 8.8, and its edible parts include the leaves, which can be eaten raw or cooked and are often added to salads or used in soups and stews. This plant's distinctive feature lies in its rapid growth rate and ability to cover large areas of water surfaces, often forming dense mats. Duckweed is known for its ornamental value and dynamic accumulator properties, making it useful in dynamic accumulator gardens. While it is not medicinal, its introduction into regions such as Ascension, Galápagos, New South Wales, New Zealand South, Northern Territory, Queensland, South Australia, St. Helena, Victoria, and Western Australia has been documented.
