Yellow Flag Iris:

The yellow flag iris inhabits temperate climates.  It can live in water up to 2.5’ and it reproduces by underground rhizomes or seeds.  This iris is used for decoration in watergardens, as an erosion control method, and in sewage treatment facilities because of its ability to remove metals from the water.  The yellow flag iris has flat, erect leaves that are arched at the top.  The flowers are 3-4’ tall on erect stems. 

The planting of the yellow flag iris is prohibited in some states due to its invasive properties.  This plant can tolerate a wide range of temperatures and salinity levels and it easily establishes itself in waterways.  It can form dense thickets similar to cattails and phragmites and can be difficult to control.
