It can grow to about 1.8 m (6ft) tall.[2] When flowering, Rumex aquaticus can be identified by its red, pink, and green 3 sepal flowers surrounding the stalk.

Habitat

Rumex aquaticus is native to temperate Eurasia. It is considered a waterside plant due to it needing nutrient rich, watery soil to grow.[3] Examples of where this plant may grow include lakeside, sides of streams and rivers, or any other environment with access to shallow water.
