It seemed everywhere I photographed this spring – I saw Yellow Flag Irises. I had always assumed they were a close relative of the various Blue Flag Irises – many of which are native to various parts of the US. I was very surprised to learn that instead of being a native plant – the Yellow Flag Irises have become an invasive species in many areas.

Originally native to regions of Europe, Asia and Africa – Yellow Flag Irises were brought to this country as a cultivated plant. Since then, many have escaped cultivation and become invasive aquatic species along ponds and waterways. And when it becomes well-established, Yellow Flag Irises are very difficult to remove on a large scale.

Yellow Flag Irises grow best in wetlands areas. They spread by both rhizomes and seeds. The plants grow to about 3-4 feet in height – with bright yellow flowers atop the stems.
