Slender spires of soft pink flowers rise above the foliage from summer through into early autumn, giving this clump-forming perennial an exceptionally long season of interest. Commonly known as Bistort, ‘Rosea’ has pointed, mid-green oval leaves that clasp the stems — a characteristic reflected in the species name amplexicaulis.

The species is native to the Himalayas; ‘Rosea’ is a selected cultivar valued for its soft pink flower colour. It thrives in sun or partial shade with moisture-retentive soil, tolerating wet conditions well — perfect for beds and borders, the edges of streams or ponds, and bog gardens. Slowly spreads over time — best given room to grow.

Plant Notes

Care Guide:
Plant in moist, fertile soil enriched with organic matter, in full sun or partial shade. Tolerates heavier soils well and is reliably hardy. Mulching annually will help maintain soil fertility and moisture retention. Once established, spreads steadily to form effective weed-suppressing ground cover. Cut back after flowering or in late winter or spring before new growth begins. Divide clumps in autumn or spring to control spread and keep plants vigorous or to propagate.
Good to Know
Wildlife-friendly — the nectar-rich flower spikes are highly attractive to bees, butterflies and other pollinators.

Adaptable and easy to grow, even in heavier soils.
