Cal-Sib Iris (CSB)

A - Z

Cal-Sib irises are the products of crosses between two iris species, Pacific Coast (Californicae) and Sino-Siberian. The Pacific Coast iris grows within a very limited range in the northwestern U.S. (west of the Cascade Mountains). Crosses with Sino-Siberian iris were made to capture the beauty of the PCI flower on a plant that can grow in a broader range.

Please note that these photo galleries are intended as a reference as well as pure enjoyment! Our photo collection has grown over many years and includes irises grown in many different locations. We DO NOT grow the vast majority of these irises!
