Saxifraga bronchialis L.
Yellowdot saxifrage, Yellow-spot saxifrage, Matted saxifrage
Saxifragaceae (Saxifrage Family)
USDA Symbol: sabr6
Yellow-spot saxifrage is a perennial rock cover with evergreen leaves. Leaf shape is extremely variable within the species resulting in plants that appear quite unalike. Leaves can be narrow and sharp-tipped with rigid hairs to rounded and spoon-shaped with soft hairs. Branched, 2-6 in. flowering stems rise above the mat of leaves, each branch terminated by a showy flower. The cream petals are dotted with round spots of varying colors.
A common plant along the mountain trails. The genus name, from the Latin saxum (rock) and frangere (to break), alludes to the species rocky habitat; the plants grow in rock crevices, looking as if they had split the rock. Accordingly, herbalists once used some species in a treatment for stones in the urinary tract.
