Persicaria virginiana var. filiformis ‘Guizhou Bronze’

From a collection made on the Loushan Pass, Guizhou, SW China, this has relatively broad foliage heavily suffused with bronze when young and with a variable brown chevron, turning to bronze tints again and then a good orangey-gold in autumn. Narrow spikes of small red flowers in October/November. Height 60 to 90cm.
