Australia’s Top Native Plants: A Natural Solution For Healthy Ponds, Natural Pools And Dams
By Julius Ewudo, Cyber Era NG ASEAN Region Representative
Australian native plants are emerging as the cornerstone for maintaining healthy ponds, offering natural water filtration and fostering biodiversity.
An esteemed aquatic biologist and founder of PASES Aqua and Auspond, Dr. Dulana Herath highlights the importance of incorporating these plants to create thriving and self-sustaining pond ecosystems.
“Native aquatic plants serve as water purifiers and biodiversity boosters,” says Dr. Herath. “By carefully selecting and integrating native species, we can balance nutrient levels, reduce algae, and enhance the overall health of pond habitats.”
The Power of Native Pond Plants
Native plants serve as nature’s water filtration system, absorbing nutrients from fish waste and decaying organic matter while shading water surfaces to reduce algae growth. Their roots stabilize pond edges, filter runoff, and oxygenate water, creating ideal habitats for aquatic life.
Key Categories of Effective Pond Plants Native to Australia:
Surface-Dwelling Plants: These floating plants purify water by absorbing excess nutrients and limiting sunlight, which prevents algae overgrowth. They also offer shade and shelter for aquatic fauna.
Top Choices:
Lemna minor (Duckweed)
Azolla filiculoides
Border Plants: These emergent plants grow with roots below the waterline but bloom above it, filtering nutrients and nitrates that feed algae. They are ideal for planting around pond perimeters or in shallow containers.
Top Choices:
Juncus pallidus
Juncus kraussii
Juncus usitatus
Baumea articulata
Baumea juncea
Baumea rubiginosa
Schoenoplectus tabernaemontani
Submerged Flora: These plants grow underwater, absorbing nutrients directly through their leaves while oxygenating the pond. They play a critical role in maintaining water clarity and ecological balance.
Top Choices:
Hydrilla verticillata
Potamogeton crispus
Potamogeton ochreatus
Ottelia ovata
Bacopa monnieri
Creating a Balanced Pond Ecosystem
Dr. Herath advises a strategic mix of surface-dwelling, border, and submerged plants to maximize water filtration and ecological benefits. He also emphasizes regular maintenance to prevent invasive growth and ensure that all plant species coexist harmoniously.
“Balancing native species in your pond ensures both functionality and beauty,” says Dr. Herath. “It’s an eco-friendly way to maintain water quality while enhancing local biodiversity.”
