Submerged Plants
Submerged plants are rooted plants with flaccid or limp stems and most of their vegetative mass is below the water surface, although small portions may stick above the water.
Some Types of Submerged Plants
American Pondweed
American Pondweed is a perennial plant that has both floating and a few submerged leaves in an alternate pattern. The floating leaves are elliptical to oval, 4-7in long and 1-2in wide on long petioles. It can be found in streams and lakes.
Baby Pondweed
Baby Pondweed can be found in neutral or slightly alkaline or brackish water of ponds and rivers, often forming large masses.
Baby Tears
Baby’s tears are a small, creeping plant which is usually completely submersed. It grows along slow-moving streams, rivers, and shallow pools. Leaves are thin, small, light green and nearly round. Baby’s tears are native to Florida.
Bogmoss
Bogmoss is native to Florida. Stems are typically several feet long, leaves are soft and mossy, densely crowded.
Brittle (Marine) Naiad
Brittle Naiad (Marine Naiad) are herbaceous annual, rooted and submersed, with a bushy appearance found in fresh or brackish waters; mostly lakes and ponds. The leaves have visible serrations and are long, pointed, and oppositely arranged on highly branched stems.
Coontail
Coontail, aka hornwort, is native to Florida. The leaves are free floating feathery and fan shaped that are rough to the touch and found in sluggish waters.
East Indian Hygrophila
East Indian hygrophila is non-native to Florida and is on the noxious and prohibited lists. It is mostly submersed with a few inches sometimes immersed above the water. Stems are square and grow to six feet long under water. Can be found in steams and slow moving waters.
Hydrilla
Hydrilla is non-native to Florida and is on the noxious and prohibited lists. Submersed but can grow to the surface and form dense mats. Found in all types of water bodies. Stems are slender and branch up to 25 feet long with small strap-like and pointed leaves.
Illinois Pondweed
Illinois pondweed is native to Florida with both submersed and floating leaves. Grows in shallow or deep waters, swift-flowing rivers or quiet lakes. Leaves are elliptic shaped and longer than they are wide.
Limnophila
Limnophila is non-native to Florida and is on the noxious and prohibited lists. It has submersed and emersed leaves. May form in dense stands from bottom to the top of freshwater.
