Saxifraga cespitosa is a perennial herb that is native to California, and also found elsewhere in North America and beyond.
California Rare Plant Rank: 2B.3 (rare, threatened, or endangered in CA; common elsewhere).
Saxifraga: from the Latin saxum, "a rock," and frango, "to break," and referring to the fact that by growing in rock crevices they appear to break rocks (contributed by Cynthia Powell)
[Wikipedia] Range, Description, Habitat, UK Protected Species: Saxifraga cespitosa, the tufted alpine saxifrage or tufted saxifrage, is a flower common to many arctic heights. It appears further south in mountainous areas of the Alps, Norway, Scotland, Wales, Iceland, Siberia, western North America and Greenland.
Densely tufted from a stout taproot, the plant has very short stems with withered, dead leaves at the base. The leaves have three to five lobes; both leaves and calyx exhibit trichomes in the form of glandular hair. Flowering stems range from 5?10 cm, with one or two flowers per stem. Its petals are white, twice the length of the calyx lobes. Smaller specimens, with shorter stems and smaller, yellowish-greenish petals (with uniflorous variants), are rather frequent.
The tufted saxifrage grows on ledges and gravelly places.
It became a protected species in the UK in 1975 under the Conservation of Wild Creatures and Wild Plants Act. (contributed by Mary Ann Machi)
