Flowers grown on inexpensive floating platforms can help clean polluted waterways, over 12 weeks extracting 52% more phosphorus and 36% more nitrogen than the natural nitrogen cycle removes from untreated water, according to our new research. In addition to filtering water, the cut flowers can generate income via the multibillion-dollar floral market.
In our trials of various flowers, giant marigolds stood out as the most successful, producing long, marketable stems and large blooms. Their yield matched typical flower farm production.

One of the most surprising things I’ve ever seen was a waste treatment lagoon covered in water hyacinths. They’re wildly invasive in some areas but they’re really pretty and apparently they’re very good at picking up things like nitrogen and heavy metals.
