White Mountain Saxifrage

Saxifraga paniculata

White mountain saxifrage is best known not as a remedy but as a survivor, a small rosette that finds a foothold in bare rock where almost nothing else will grow, then edges its leaves with tiny beads of lime drawn up from the stone itself. Its genus name comes from the Latin saxum, meaning rock, and frangere, to break, a nod either to how the roots seem to split stone or to an old medieval belief, applied broadly across the saxifrage family, that a plant capable of cracking rock could likewise dissolve stones forming inside the body. That doctrine-of-signatures idea attached itself more firmly to a few cousin species in the genus than to this one, and White mountain saxifrage itself was never widely taken up as a folk remedy. Instead it earned its keep for centuries in cottage rockeries and alpine troughs, admired simply for holding its ground and its color through hard winters.

Safety.

White mountain saxifrage isn't known to be toxic, but it also has no established history of food or medicinal use, so there's no safe dose to offer. Don't eat wild-collected plants without expert identification, since similar alpine rosettes are easy to mix up.
