Northwest Wildflowers

A collection of information about the native plants of North America — especially the wildflowers of Oregon, Washington, and northern California

May 2023: This is the latest spring in many years for most of Oregon, Washington, and California. Most low-elevation locations west of the Rocky Mountains are a few weeks behind their usual schedule — although the mid-May heat wave did move things along a bit.

As for the outlook for the rest of the year, the snowpack in most of Oregon is above normal, and Washington is normal or a bit below normal. California, Nevada, and Utah are in great shape.
