Water gardens add a serene and captivating element to any outdoor space. These aquatic ecosystems not only enhance the visual appeal of your garden but also create a thriving habitat for various plants and wildlife.
Aquatic plants play a crucial role in maintaining the balance and beauty of water gardens. They offer aesthetic value and environmental benefits.
When selecting aquatic plants for your water garden, it’s essential to consider factors such as sunlight requirements, water depth, and growth habits.
Some plants thrive in shallow water, while others prefer deeper areas. The size of your water feature also influences plant selection, as certain species can spread rapidly and may overwhelm smaller ponds.
We researched and evaluated numerous aquatic plants to identify the top choices for water gardens. Our selection focuses on plants that are easy to maintain, visually appealing, and beneficial to the overall health of your water garden ecosystem.
Top Aquatic Plants for Water Gardens
We’ve curated a list of the best aquatic plants to enhance your water garden. These plants not only add beauty and visual interest but also help maintain water quality and provide habitat for aquatic life.
Our selections cover a range of sizes, colors, and growth habits to suit various water garden designs.
Our top pick
- Native to much of the U.S., so it supports local wildlife without invasive risk
- Winter hardy (listed for USDA zone 5) and tolerates sun or shade
- Marginal plant that helps filter pond water; seeds feed wildlife such as ducks
Cons
- Marginal plant, not a floating-leaved lily—needs shallow water or a plant shelf
- Ships as a single plant at a higher price than bare tubers
- Fewer ratings than mass-market pond plants
Arrow arum gives a water garden bold, tropical-looking foliage along the edge while staying a native choice, and its calla-like flowers are followed by seed heads that wildlife eat.
Grow it in shallow water, a bog area or on a marginal plant shelf; it is a low-maintenance perennial that helps keep pond water clear naturally.
Skip this one: Water Hyacinth
We no longer recommend water hyacinth (Eichhornia crassipes). It’s a federally listed noxious weed that’s illegal to sell, possess, or transport in many states, and it escapes ponds easily, forming dense mats that choke waterways and crowd out native aquatic life. The fact that a retailer will ship it to you doesn’t make it legal to grow where you live, so check your state’s noxious/invasive plant list before buying anything like it.
For surface cover that won’t cause this trouble, look for a native floating-leaved plant like American white waterlily (Nymphaea odorata), which shades the water and gives fish cover without the invasive risk.
Best budget option
- Reproduces quickly through runners
- Acts as a natural biofilter
- Adds visual interest to water gardens
Cons
- Not native to North America and spreads quickly, so keep it contained and out of natural waterways
- Sensitive to frost and extreme heat during shipping
- Ships in a small 2-inch pot, sometimes with trimmed roots
Water poppy is a fast-spreading floating-leaved plant that helps shade and filter pond water at a low price.
It is frost-tender and the seller warns against ordering in extreme heat or cold; plant it in calm, shallow water and thin it as it spreads. Because it is non-native, never let it escape into ditches, streams or natural ponds.
Skip this one too: Water Hyacinth Trio
Don’t buy water hyacinth. Water hyacinth (Eichhornia crassipes) is a federally and state-listed noxious invasive that’s illegal to sell, possess, or transport in many states, including by mail order. Once it escapes a pond into a ditch, pond, or waterway, it spreads aggressively and forms dense floating mats that block sunlight, starve fish of oxygen, and crowd out native aquatic plants.
Instead, look for a native floating-leaved pond plant like American white waterlily (Nymphaea odorata) for similar surface shade without the legal or ecological risk.
Also great
- Non-GMO and heirloom varieties
- Suitable for bowls, containers and ponds
- Inexpensive way to experiment with aquatic plants
Cons
- Limited planting instructions included
- Requires patience and care to germinate
- Seed-grown plants take much longer to bloom than tubers or potted plants
These 30 mixed seeds are a budget way to try growing miniature water lilies and lotus in a bowl or small pond.
Expect a slow start: germination takes care and patience, and instructions are minimal, so look up planting guidance before you sow.
Buying Guide
When selecting aquatic plants for your water garden, consider these key factors:
Light Requirements
Choose plants that match the sunlight conditions of your garden. Some thrive in full sun, while others prefer shade.
Hardiness Zones
Ensure the plants you select can survive in your climate. Check your local hardiness zone and compare it to the plant’s requirements.
Water Depth
Different aquatic plants have varying water depth needs. Match the plant to the appropriate depth in your pond or container.
Growth Rate
Consider how quickly the plant grows. Fast-growing species may require more maintenance but can quickly fill empty spaces.
Size at Maturity
Select plants that fit your water garden’s size. Some may outgrow small spaces, while others remain compact.
Compatibility
Choose plants that coexist well together and with any fish in your water garden.
Maintenance Needs
We recommend considering the care requirements of each plant. Some need regular pruning, while others are low-maintenance.
Purpose
Determine the plant’s role in your water garden:
| Purpose | Examples |
|---|---|
| Oxygenation | Submerged plants |
| Surface coverage | Floating plants |
| Visual interest | Emergent plants |
| Filtration | Marginal plants |
By carefully considering these factors, we can create a thriving and balanced aquatic ecosystem in our water gardens.
