Alpine pearlwort is a delicate, mat-forming perennial that naturally colonizes rocky, alpine, and subalpine environments across the Northern Hemisphere. It thrives in cool, moist, well-drained conditions with partial shade, making it a charming filler for rock gardens, crevices, and alpine troughs. Minimal care is needed beyond ensuring consistent moisture and avoiding compacted or overly rich soils.
