Bohemia Ecological Preserve

The Ground Iris is a short plant that grows on hillsides in oak-madrone woodlands. It is native to north central California and is not found on the coastal bluffs. Inland it hybridizes with Douglas Iris and both can vary quite a bit in flower color, ranging from white to yellow to lavender-blue. The Douglas Iris plant is larger and grows in larger clumps.
