Pond Sense and Plant Science
Are you trying to figure out which Michigan pond plants actually belong in your water and which ones cause more harm than good? Wondering how aquatic plants affect algae growth, fish, and the overall health of your pond?
In this guide, you’ll learn how different water plants function, which species are native plants versus invasive aquatic plants, and how to identify what’s growing in your pond.
By the end, you’ll know how to make smarter plant choices that improve water quality, support wildlife, and keep your pond balanced year-round in the Great Lakes region.

Main Types of Pond Plants
Submergent Plants and Algae
Submerged plants grow entirely below the water surface, rooted in sediment or free-floating in the water column. Their submerged leaves absorb nutrients directly from the water and help stabilize sediment.
Algae are technically aquatic plants too, but they behave differently. Some algae float freely, while others attach to surfaces.
When nutrients and sunlight are out of balance, algae growth can quickly become thick and harmful, especially during warm summer periods.
How else can you control algae in your koi pond?
Floating Plants
Floating plants sit at the surface and may or may not have roots.
Some are rooted in shallow areas, while others are true free-floating plants that drift with wind and wave action.
Floating vegetation provides shade, limits sunlight penetration, and helps cool the water.
In moderation, this reduces algae.
In excess, it can block oxygen exchange and stress fish.
Emergent Plants
Emergent plants grow in shallow water with roots submerged and stems, leaves, and flowers above the surface. These plants dominate pond edges, marshes, and wetlands.
They provide shelter for wildlife, stabilize shorelines, and create habitat for ducks, insects, fish, and other wildlife.

Submergent Pond Plants in Michigan
Many submerged plants are native and beneficial.
- Muskgrass grows in low mats and helps filter nutrients from the water.
- Pondweeds are a diverse group with submerged and floating-leaf forms that support fish and wildlife.
- Wild celery has long, ribbon-like submerged leaves that sway with currents and offer shelter for fish.
- Coontail floats freely without roots and provides cover in deeper water.
- American elodea is another common submerged plant that oxygenates water and supports aquatic ecosystems, especially in spring and early summer.
These native plants help maintain oxygen levels, reduce sediment movement, and support the pond food web.
Invasive Submergent Species of Concern
Some submerged plants are invasive plants that spread rapidly and outcompete native species.
- Curly-leaf pondweed begins growing in the fall and winter.
- Eurasian watermilfoil forms dense surface canopies that block sunlight and crowd out other aquatic plants.
- Hydrilla is a highly aggressive invasive species capable of forming thick mats from the bottom to the surface.
These species reduce oxygen, interfere with fish movement, and alter habitat across ponds, lakes, and slow-moving rivers.
Floating Pond Plants in Michigan
Duckweed consists of tiny floating plants that can multiply rapidly. While small amounts help absorb nutrients, unchecked growth can blanket the water surface.
Water lilies and spatterdock have large floating leaves that provide shade and help moderate water temperature. Their flowers grow above the surface and support pollinators while creating visual interest in pond gardens.
Some floating plants commonly discussed elsewhere, such as water lettuce, water hyacinth, and water spangle, are tropical and not native to Michigan. These free-floating plants struggle to survive winter conditions and are regulated due to their ability to spread and harm ecosystems.
Emergent Pond Plants in Michigan
Cattails, pickerel weed, arrowhead, and bulrush are classic emergent plants found in shallow water and marshes.
Pickerel weed produces blue flowers and thrives in full sun.
Arrowhead has distinctive leaves and underground tubers that support wildlife.
These plants anchor pond edges, reduce erosion, and create shelter for fish and amphibians. Emergent plants also trap nutrients before they enter open water, improving clarity and reducing algae.
Invasive Emergent Species
Phragmites grows extremely tall and forms dense stands that crowd out native wetland plants.
Purple loosestrife spreads through seeds and roots, quickly dominating shallow areas and marshes.
Both invasive plants reduce biodiversity and disrupt wildlife habitat, particularly in wetlands connected to lakes and streams.
Regulated Invasive Aquatic Plants in Michigan
Prohibited Aquatic Plants
Several invasive aquatic plants are prohibited due to their ability to spread rapidly and cause ecological harm.
- African oxygen weed forms thick underwater mats that interfere with water flow and fish movement.
- Carolina fanwort has finely divided submerged leaves and grows aggressively in still water.
- European frog-bit floats freely and forms dense mats on the surface.
- Giant salvinia is a floating fern that blocks light and oxygen exchange.
- Didymo, often called rock snot, coats surfaces with thick mats that smother habitat.
- Cylindro is a type of algae that clouds water and disrupts ecosystems.
Restricted or Watch List Species
Some invasive species are restricted or monitored due to their potential to spread.
Flowering rush produces umbrella-shaped flower clusters and thrives in shallow water.
Brazilian elodea and European water clover are monitored because of their ability to establish quickly.
Hydrilla and Eurasian watermilfoil remain high-risk invasive species due to their fast growth, ability to survive winter, and tendency to dominate water bodies if left unmanaged.
