Clump of Persicaria / Bistorta (Glyne Gap TN40)

One clump of persicaria aka Bistorta. I don't know the exact variety but red flowers and growing to 120cm high. Just dug up. (I left dividing late as the persicaria was still flowering until two weeks ago.) Not a showy plant but useful for background height and colour and easy to maintain. I can leave outside for the assigned person to collect as convenient but the sooner it is back in the ground the better. Paul
