Hot rock daisy is a California native perennial ranked 4.3 by CNPS, found in the California Cascades and Modoc Plateau in loose sandy areas, lava beds, and forest edges at elevations of 1,100 to 2,000 meters. Flowering from June to August, this plant produces white to pale lavender daisy-like flowers in small clusters. Growing with decumbent to ascending stems 10 to 20 centimeters tall that are reflexed-hairy near the base, it forms low-growing clumps. Its leaves are stiff-hairy and ciliated, with proximal and middle leaves showing distinctive hair patterns. The plant's compact form and ability to thrive in harsh rocky environments make it a notable wildflower of volcanic landscapes.
