Tall reeds growing at the edge of a wetland.

Clue explained

A reed is a tall, grasslike plant that grows in or near wetlands. Reeds and other wetland plants can help filter water: they slow its movement, trap sediment, and provide places for microbes around their roots to break down some pollutants. That makes reed-filled wetlands useful in natural water-treatment systems, though the plants are part of a larger filtering process.
