Comments: California Chicory is a showy spring bloomer found at higher elevations than its close and similar looking relative, New Mexico Plumeseed, Rafinesquia neomexicana. California Chicory blooms a little later in the spring. Other differences involve the lengths of the white florets and the outer bracts (phyllaries) which grow side by side.
In California Chicory, the white and pinkish colored bracts are slightly but noticeably shorter than the length of the white florets.
Another similar species is the more common Tackstem, Calycoseris wrightii has larger white flowers and visible tack-shaped glands under the flower head. The name Chicory is a result of its similarity to the flowers of Common Chicory, Cichorium intybus which is bright blue and found throughout Arizona and the United States.
