Description

Not to be confused with duckweed Lemna minor. This floater is larger in size. This one is much easier to manage and remove from your aquarium.

Transform your pond or water garden with Giant Duckweed, a versatile and attractive aquatic plant. Here’s why you’ll love it:

  • Appearance: This free-floating perennial forms a lush coverage on the water surface of small, oval to rounded, deep glossy green leaves with a distinctive red dot on top and dark red undersides. Each plant consists of 2 to 3 leaves, connected with up to 3-15 minute roots hanging beneath.
  • Benefits: Giant Duckweed is not just beautiful; it’s functional too! It helps control mosquito larvae, removes pollutants like phosphorus and nitrogen from the water, and provides a crucial food source for ducks, turtles, muskrats, beavers, birds, and fish.
  • Growth: Known for its rapid multiplication, it creates dense colonies that can cover the water surface, providing shade and reducing algae growth. However, it’s easy to manage with regular removal using a net.
  • Ideal Conditions: Thrives in full sun to part shade on still water in ponds, lakes, and slow-moving streams. In the aquarium, they do best with direct light from lighting and not tossed around by filters.

Enhance your aquatic space with Giant Duckweed and enjoy a healthier, more vibrant water garden!
