For Sumpfpflanzen , I recommend a minimum of one basket (4 plants) and a maximum of 4 baskets (16 plants) per m³ (1000 gallons of water). The amount needed depends on how quickly you want the pond to balance and your visual requirements.

Sumpf schwertlilie

The yellow iris, often referred to simply as the Sumpf schwertlilie , is a true hero along the waterfront. This water-loving plant, which grows naturally along European waters, not only adds color to your pond edge with its bright yellow flowers, but also works hard to keep the water clean.

Iris pseudacorus

With a growth height of up to about 80 centimeters, the yellow iris is a striking element in any water feature. It can be a real eye-catcher both along the edge and in the middle of the pond.

Iris flower yellow

The yellow iris does more than look pretty. The plant has a clever root system with a special layer rich in beneficial bacteria. These help absorb excess nutrients from the water, such as nitrates, which can reduce algae growth.

Iris care

In terms of care, the yellow iris is not demanding. It can stand the cold well and needs little maintenance. In autumn it is smart to cut the spent stems, but otherwise it mainly takes care of itself. This makes it an ideal choice for those who want a low-maintenance but reliable and beautiful plant in the pond that blooms every year.

Iris pond

The Iris aquatic plant plays a crucial role in the natural filtration of pond water, through its root system that helps absorb excess nutrients and potentially harmful substances. This absorption helps reduce algae growth and contributes to clearer, cleaner water, which is essential to the health of the pond ecosystem. In addition, the Iris plant's dense growth provides a physical barrier against sediment and debris, keeping the water surface calmer and more visually appealing.
