Yellow Flag(Iris Pseudacorus) showing off. Very large Iris removed from a water mitigation site in California. Growing in about a foot of water.

I am a Iris lover. Amazing how they are found in so many different environments. Are those the type that remove heavy metals?

Cattails are probably best for heavy metal removal Bill. Simply because of their biological mass production. These iris would have a similar effect once established. The iris have an advantage in that they can treat effluents 365 days out of the year as opposed to cattails that go thru a dormancy. Have planted mitigation wetlands for: Nitrates from bomb pollution Chicken egg processing effluent aluminum and copper mine runoff Sewage treatment Gas station run off Silt catchment ponds Retention ponds Red Cross blood treatment effluent Commercial parking lot runoff And some places that are best not mentioned or forgotten.
