Summary

River Beauty is a dwarf, rhizomatous perennial forming clumps with erect to ascending stems 5–30 cm tall, woody at the base, with circumboreal distribution across northern regions and natural habitat along moist river gravels and damp slopes, bearing pink to rose, four-petaled flowers.

In cultivation, it prefers sun to partial shade and consistently moist soils that are well-drained or moisture-retentive, tolerating alkaline to acidic conditions; propagation is by seed sown in early spring or by division and can spread via spreading roots, with wind-dispersed seeds promoting rapid spread, so deadheading seed capsules is advised to prevent unmanaged spread; valued for ornamental appeal near water and for attracting bees.
