Native Irises in Washington State

Learn all about native Irises growing in Washington State, like how to identify and manage them in our landscape, from experts at the Washington Native Plants Society.

Learn about native Irises growing in Washington State: how to identify our regional species, like western blue-flag, Oregon flag, grass-widows, and blue-eyed grasses. What are their ideal habitats? Where do they grow? Why are blue-eyed grasses even in the Iris family?

Learn hands-on tips to distinguish each species and find out if any can thrive in home gardens or managed landscapes. We’ll also look at the invasive yellow-flag Iris and its persistence in Washington, highlighting the latest research and efforts to eradicate it. Sarah Verlinde-Azofeifa is a native plant botanist and educator, affiliated with the Washington Native Plant Society (WNPS) and the University of Washington. She is currently the Program Coordinator leading the WNPS Northeast Stewards program, a group of dedicated volunteers helping to restore three parks within the City of Spokane.
