Lemna Minor is also known as Duckweed. Whether you realize it or not, you have likely observed duckweed floating across the top of a lake on more than one occasion. The great allure of duckweed is that it grows very quickly and requires no effort to maintain, unlike many other fast-growing plants. Because it rests at the top of the water in which it grows, it can be relied upon to provide shade and shelter to breeds of fish that require it. It is also a popular choice of snack among certain herbivores. Sold as a small loose portion. Portion size: 2"x2" Pictures are not the actual plants you will receive, but a sample representation.
