Persicaria amplexicaulis ‘Rosea’ is a pink variety of Persicaria amplexicaulis, it is also known as Bistorta amplexicaulis, Polygonum amplexicaule ‘Roseum’, Mountain fleece and part of the Polygonaceae family of plants. It is a deciduous, clump-forming plant, so you can propagate it by division. It does well both in full sun or partial shade so you can use it in many areas in the garden landscape.
Persicaria amplexicaulis ‘Rosea’ looks wonderful with its spikes of the light pink flower in late spring, summer, and fall. It is a wonderful plant for borders or a wildlife garden. I saw this at Potters Field Park in London, UK. It usually grows to 4ft and does well in both poorly-drained or well-drained soil rather easy to grow. It attracts birds and butterflies to your garden. However, it is rabbit and dear resistant and easy to grow, no disease or pests have ever been reported. You can prune back after it flowers.
