Alisma (Water Plantains)
The Alisma genus, commonly known as water plantains, provides valuable habitat and food for UK wildlife. Its broad leaves offer shelter for aquatic invertebrates, while its delicate white flowers attract pollinators like bees and hoverflies.
Birds such as moorhens and ducks feed on the seeds, and the plant’s shallow-water roots help stabilise pond edges. Alisma thrives in wetlands, supporting a balanced ecosystem by improving water quality and providing cover for amphibians. This hardy perennial suits naturalistic planting schemes and thrives in both still and slow-moving water.
Frequently Asked Questions
When is the best time to buy pond plants in the UK?
Spring is the ideal time to add plants to your pond, as warmer temperatures encourage strong growth. We suggest purchasing between mid-February and March, to give your pond plants plenty of time to establish roots and adapt to their new environment before summer.
Which pond plants help oxygenate water?
Plants like hornwort and water crowfoot are excellent for boosting oxygen levels in ponds. They absorb carbon dioxide and release oxygen, helping to keep the water clean and healthy for fish and other wildlife.
How do I choose the right pond plants for my pond size?
For small ponds, select compact plants like dwarf water lilies and small irises to keep the space well-balanced without overcrowding. Large ponds benefit from a mix of floating plants like water hyacinth, which covers a broad surface, and larger water lilies that provide shade.
How can I attract more wildlife to my pond with plants?
Planting marginal plants like marsh marigold provides shelter for frogs and insects, while oxygenating plants like hornwort improve water quality, creating a healthier habitat for aquatic life. Choosing a mix of plants that bloom at different times of the year ensures your pond remains a thriving, wildlife-friendly environment throughout the seasons.
