Gaudinia fragilis is the most widespread species of the genus in the Mediterranean region. Its presence in the Western Hemisphere was first documented in 1991 by a collection from Sonoma County, California, where it was found growing on an open grassy hilltop in thin, rocky soil of open oak woodlands, in a region that has long been used for agriculture.
