Did you know that the Orleans Iris or Ishi-Pishi Iris - Iris tenax klamathensis -  is a rare plant?  It is!  Iris tenax klamathensis.jpeg

This special yellow blooming iris is only found here, nowhere else in California or Oregon, or the entire world. In fact it is commonly seen only on the west side of the Klamath River between Orleans and Somes Bar. In the past few weeks the sides of Ishi Pishi Road have been bejeweled by this iris.  But the irises you see up the Salmon River, or toward Weitchpec or Happy Camp are different species.

Iris tenax ssp. klamathensis is an example of an endemic plant.  Endemism is when an organism has a restricted range, found in only one region and not outside of that location.  The Klamath Siskiyou biogregion is home to many endemic species because of its unique geography.  And to me, the Orleans Iris is the flower shaped shining star that reminds me how special this place we live really is.
