The Rock Soapwort is the hardiest and heaviest blooming plant of this genus. Its long, trailing stems form a mound or a mat and in late spring and summer the deep pink, 5-petaled flowers emerge. These vivid blooms attract butterflies and its dainty size makes it a good front of the border plant in a butterfly garden. The common name originated from the leaves which when bruised, produce a soap-like lather. Performs best in full sun and well-drained soil, but will tolerate poor, dry soil. Prune hard after flowering to keep compact and to encourage new growth. Good for trailing over walls, rock gardens
