While visiting the Golden State in April of this year, I encountered several examples of this fine plant. It is characterized by its narrow, gray-green leaves and flowers that range in color from creamy white to pale yellow, often with darker yellow veins and a yellow signal.
Fernald’s Iris is found in the Northern California Coast Ranges, including the Santa Cruz Mountains and the San Francisco Bay Area, where it frequents dry, lightly shaded areas in the northern and southern coastal mountains. It lives only in California.
Plants grow individually in the filtered light of a protective oak canopy, and extend slightly outward into the grasslands along forest edges. I saw examples in roadside fields as well as along woodland mountain trails.
Irises are perennial plants, growing from rhizomes (underground root systems that send out roots and shoots from its nodes) or, in drier climates, from bulbs. They have long, erect flowering stems which may be simple or branched, solid or hollow, and flattened or have a circular cross-section.
In colorful magazines promoting California’s wine industry, the Fernald’s Iris is sometimes called the “Little Yellow Wild Iris.” “Wine Country Iris” would be equally appropriate, since its distribution coincides closely with the best wine producing regions in the central coast.
