It blooms profusely throughout the summer and is very winter-hardy (USDA Zones 4a–8b), making it excellent for northern climates. The plant spreads effectively via root suckers, forming dense thickets, which is why it is also used as ground cover and for erosion control on moist slopes.
Great Duckweed
Spirodela polyrhiza
Great Duckweed (Spirodela polyrhiza) is a tiny free-floating aquatic plant from the Arum family (Araceae, subfamily Lemnoideae). Its round to oval fronds measure only 2–10 mm; they are fresh green on the upper side and reddish-purple on the underside. Unlike related duckweed species, each frond produces 7 to 21 thin roots (instead of the usual one), allowing it to float easily on the surface of stagnant or slow-moving waters and form dense mats. It reproduces primarily vegetatively by budding new fronds from the mother plant, flowering only rarely. In autumn, it produces turions—starch-rich storage buds that sink to the bottom to overwinter, resurfacing and germinating in spring when water temperatures reach around 15 °C. It is one of the fastest-growing flowering plants in the world and is found in the wild almost globally.
Yellow Mombin
