Siberian Iris of the UC Berkeley Botanical Garden

Photographed by Ken Walker


Siberian iris are, for the most part, native to asia. They are divided into two groups: those with 28 chromosomes, including the familar garden siberians, and those with 40 chromosomes. That later are sometimes called sino-siberians because they are mostly native to China. Most of the siberian iris in the UC Berkeley Botanical Gardens are sino-siberians.
Iris bulleyana
 Iris bulleyana. Some references describe this iris as a probable hybrid of questionable origin, with I. chrysographes and I. forrestii as likely parents. But Zhao Yu-tang, in Iris of China, give its native range as Shicuan, Yunnan, and Tibet provinces.

Iris sp., Xizang Province
 This is an undentified species from Xizang Province, China (Tibet). I've included it here because, to me, it looks similar to the sino-siberians, particularly I. chrysographies.
