Aquatic Weed Identification

Floating Aquatic Plants

True Floating Plants are not attached to the bottom. Floating plants come in sizes from very small (Duckweed) to over a foot in diameter (Water Hyacinth). Most have roots that hang into the water from the floating green portions.

Submerged Aquatic Plants

Submerged Plants are rooted plants with most of their vegetative mass below the water surface, although some portions may stick above the water. One discerning characteristic of submerged plants is their flaccid or soft stems, which is why they do not usually rise above the water's surface.

Algae are very primitive plants. Some algae are microscopic (Planktonic algae), others are thin and stringy or hair-like (Filamentous Algae), while still others are large and resemble higher plants but without true roots (chara).
