Northwest Wildflowers

A collection of information about the native plants of North America — especially the wildflowers of Oregon, Washington, and northern California
Wildflower Update, September 2022: It's been a strange year. After a fairly normal winter, the spring months were very cold, and the flowers in most locations started late. Then, repeated heat waves in July and August accelerated things to the point that the spring delay was almost completely canceled out. The end result was a very short wildflower season.
There are two types of places where you might find wildflowers in September: muddy riverbanks that were underwater all summer (e.g., Rooster Rock), and along snowmelt-fed streams in the high Cascades (e.g., the Mount Baker area).
