Plants that favour a damp or wet environment. We can find several of these where we currently live in Iceland due to the wet climate, and peat soils.
A wetland for greywater treatment could consist in a first tank where sewage from a settlement tank flows in a tank filled with coarse gravel, and topped by fine gravel and sand, and Phragmites australis. The water sinks and at the bottom flows into another downstream tank, with aeration pipes, and Iris pseudacorus growing in that water, Clean effluent flows at the bottom.
First we list plants that grow in wet meadows and banks, then plants that grow around water edges, and finally plants that grow in the water:
