The blue to purple flowered plants formerly were included in Iris thompsonii
, and recent authors confirm the separation of these closely allied species. More recently, Iris thompsonii
was separated out on non-flower-color characters, retaining cream and warm color forms for I. innominata
grows in southern Oregon in Coos, Curry, Douglas and Josephine Counties, on serpentine soils, in shaded to partly shaded sites. It hybridizies naturally with other species found in this area, including I. tenax
, I. douglasiana
, I. chrysophylla
and I. bracteata
. This species grows over a wide range of elevations, and confers both hardiness and color to hybrid PCIs.
| Louis Forniquet Henderson separated the blue forms as Iris thompsoni and the yellowish forms as Iris innominata in Rhodora, xxxii. 23, 1930 Later botanists combined them but they were again shown to be distinct species by Carole Wilson.
