The Bog Bean (Menyanthes trifoliata) is a vigorous native aquatic perennial, perfect for large ponds, lakes, and natural landscaping projects. From April to June, it produces delicate white, star-shaped flowers with fringed petals tinged with pink, attracting bees and other pollinators. Its trifoliate, olive-green leaves provide excellent surface coverage, offering shelter for aquatic wildlife such as amphibians and aiding in algae control. Thriving in full sun to partial shade, this hardy plant is a valuable choice for enhancing both the ecological balance and visual appeal of larger water features.
Not suitable for small ponds due to its vigorous growth habit.

Caution: All parts of Menyanthes trifoliata are toxic if ingested.

    Marginals - Good to Know

    How Deep Should I Place My Marginals?

    The planting depth depends on the variety. Check the product page or the care label included with your plant for specific guidance.

    Depth is measured from the top of the pot to the water’s surface.

    Most marginals are fine placed 1cm to 2cm under the waterline, just enough to hide the aquatic basket.

    How Many Marginals Do I Need?

    Measure the length of your marginal shelves and then allow:

    • 1ltr Plants: 5 per linear metre
    • 3ltr Plants: 3 per linear metre

    Tip: Leave space between plant varieties to prevent dominant species from taking over. For more details, see our Planting Guide.

    Do I Need to Line My Basket with Hessian?

    No, Finofil aquatic baskets are designed with a fine mesh that prevents soil loss. Adding a liner is optional but not necessary.

    What Are Finofil Baskets Made From?

    Finofil aquatic baskets are made from 100% recycled plastic and manufactured in the UK. They can be recycled at local recycling centres or through kerbside collections that accept black plastic. Plant labels are also recyclable.

    Will Carp or Ducks Eat My Plants?

    Carp (inc. Koi): These fish find pond plants irresistible! If you have carp, we recommend protecting your plants with barriers.

    Goldfish: Goldfish may nibble on oxygenators and softer plants but generally cause less damage. They also eat insects, larvae, and tadpoles.

    Wildfowl: Ducks and other birds may eat plants or damage roots while nesting. Mature plants with strong root systems are more resilient, but consider protecting roots/rhizomes for added security.
