Bankweed

TL;DR | Shore weed (Littorella uniflora) is a rare, native aquatic plant that is at home on the boundary between land and water. This evergreen plant grows as a compact rosette along nutrient-poor banks, dune pools and fens. Its unique shape, sturdy leaves and ability to survive underwater without flowering make it an interesting choice for the ecological pond.

Bankweed (Littorella uniflora): Unique rosette plant for nutrient-poor banks

Bankweed is a special little plant that has a permanent home in nutrient-poor wetlands, fens and dune ponds. This small, rare plant is not easily noticed but plays an important role in the biodiversity of natural ponds. With its compact growth habit, remarkably sturdy leaves and ability to survive underwater, Bankweed is a unique asset for any ecologically designed pond.

  • Bloom: June to August
  • Flower colour: Straw-coloured to whitish
  • Hardy: Yes, even stays green under water
  • Indigenous: Yes (Netherlands, Belgium, Western and Northern Europe)

Growth and spread

Shore weed grows from short rhizomes that form offshoots. Compact rosettes form from these offshoots and may loosely expand along wet banks or at the bottom of shallow water. In fully submerged conditions, the plant remains vegetatively active but does not flower.

On the border of dry and wet conditions, Bankweed can actually bloom. The inflorescence is a combination of long male flowers on filamentous stems and one to three female flowers at the base. Pollination is by wind, with the feather-shaped stigmas collecting pollen from the air.

Where does Bankweed grow?

Naturally, you can find Bankweed on:

  • Moist sandy soils
  • Peaty banks
  • Dune pans with clear, nutrient-poor water
  • Fens in the higher sandy soils
  • Drying pools in late summer

In the Netherlands, the species still occurs regularly on the Wadden Islands and in Zeeland, but elsewhere it has declined sharply. In Belgium, the plant is even very rare.

The role of riparian weeds in the pond

Bankweed is not often chosen for traditional garden ponds, but it fits perfectly into ecological, clean water environments with little nutrition. Due to its evergreen nature and preference for clean, clear waters, it helps maintain a stable and ecologically healthy pond environment.

Note that the plant requires little nutrition and does not like nutrient-rich water. In an over-fertilised pond with many fish, Bankweed will not feel at home.

Care and application

  • Maintenance: Little to no maintenance required. Decomposed parts can optionally be removed in spring.
  • Combinations: Combines well with other rare marsh plants such as marsh deer hay, stiff marsh plantain, common water marsh, pilferrey and floating rush.
  • Planting: Preferably in pond baskets filled with sand or pond substrate.
  • Nutrition: Additional feeding is not necessary. The shorebird gets everything it needs from the soil or water.

Why choose Oeverkruid?

Bankweed is not a typical pond plant. This species is meant for the true lover of natural pond biotopes. It is rare, hardy and ecologically valuable. Those who want to enrich a nutrient-poor pond with a native species with few requirements will find a reliable ally in Bankweed.
