Persicaria amplexicaulis is an excellent perennial bistort for late colour. Many pink-red spikes of flowers emerge from mid-summer and through the autumn from a dense covering of puckered ovate leaves.
At the Garden, it is combined with china blue asters in the Autumn Garden and is at home in the Polygonaceae beds on Systematics. There is also a great stand of this dependable plant, commonly known as Mountain Fleece, by the Lake edge, backed across the water by the copper foliage of the Swamp Cypress.
