Endemic wildflowers of the Siskiyou Crest!

Fritillaria glacua (Siskiyou fritillaria) growing from rocky scree on Goodbye Ridge in the Kangaroo Roadless Area

Summer in the Siskiyou Mountains is prime time to enjoy the region’s renowned botanical diversity. Whether hunting rare wildflowers or enjoying common, yet colorful species, the Siskiyou Crest offers some of the West Coast’s most diverse flower displays. Many species found in the region are endemic to the area, meaning they are found only in the Klamath-Siskiyou Mountains. In this post I have featured a few species endemic to the Klamath-Siskiyou Mountains. Look for them while you are out and about this summer.
