About Iris innominata L.F.Hend.
Iris innominata, commonly called the Del Norte County iris, is a species of iris. It is native to southern Oregon, as well as northern coastal California and the Klamath Ranges in Del Norte County, California. This iris produces dense, evergreen leaves that grow up to 20 cm long. Its flowers are typically deep golden yellow with darker veins, though flower color can vary between individuals. Flower stems grow to around 12 cm tall, and usually produce 1 to 2 flowers in spring. It is included on List 4 (Limited distribution, Watch List) of the California Native Plant Society Inventory of Rare and Endangered Plants of California. When grown in gardens, Iris innominata thrives best in locations with cool, wet winters and warm, dry summers. It prefers neutral or slightly acidic soil with good drainage, and can grow in full sun or partial shade. It is often used to create new hybrids by crossing it with other iris species. Many plants sold under this name at nurseries are actually hybrids, not pure Iris innominata.
