The Lake cress is a small amphibious plant from North America, known as aquarium plant for many years. When this small plant is grown submerged, it has a rosette-like habit or develops a short stem. The submerged leaves are hard, somewhat brittle and have a very variable shape. With its height of about 10 cm, this plant is recommendable as accent in the foreground. Rorippa aquatica is undemanding and slow growing. Moderate temperature (up to 25 °C) and nutrient-rich substrate are recommended. It can be propagated by adventitious plantlets which develop on the petioles of broken off leaves floating at the surface.
