Smart Weed is a great addition to any lake or pond

Smart Weed (Polygonum hydropiper) is a very common moist soil wetlands perennial plant that grows on wet, saturated soils typically on and close to the ground as a ground cover that likes to grow in dry and sandy soil. Smart-weed is commonly found in marshes, swamps, wet forests and ditches. It grows most commonly in hardiness zones 8-11. However, Smart-weed is also an excellent waterfowl food plant because it provides a sufficient level of great seeds for a variety of waterfowl like diving and dabbling ducks.

Submerged portions of this plant provides habitats for many micro and macro invertebrates. 

Smart Weed has a branched stem that grows from two to three feet long. The growth is slower in the beginning stages, and then begins to develop semi-erect, and the rate of speed can become very rapid in the right environment. Growing 2 to feet tall or long they can have each of the different growth forms and were once believed be two different species, but research has shown that no matter which growth form occurs they are of the same species that grow differently under different conditions, above water and below. Leaves are shaped like a lance with a sharp tip and short stalk with hairs. They blossom a pinkish drooping small oblong ball-shaped flower. The leaves are edible and have the bitterness to them that resembles peppermint only odorless.

There are values Smart-weeds provide to humans.

Native Americans used them as a food source, and other groups utilized the stems, roots, and leaves for medicinal purposes. Some scientist believes the name Smartweed derived from the “smart” which was the name of a plant in medieval times utilized to relieve swelling and itching of the human rear end.

Also known informally as Knotweed from the buckwheat family and was named by Antoine Laurent de Jussieu back in the late 1780’s because of the swollen nodes that develop along the stems of the plant. Deriving the name from the word poly which means ‘many” and the Greek word goni referring to a joint or knee.
