Yellow Flag Iris (Iris Pseudacorus)

About Yellow Flag Iris

Yellow Flag Iris is a rapidly spreading invasive species that threatens native wetland vegetation. It blocks water flow, damages bird nesting sites and invades important fish habitat. The plant spreads by long rhizomes and by floating masses of seeds. It is easy to spot with its sword-like leaves that have sharply pointed tips and bright yellow flowers that appear in late spring and early summer. At maturity it can reach 1.5 m (5ft) in height. It contains poisonous plant resins that can cause a variety of human skin irritations as well as illness in grazing animals.
