Sanguisorba officinalis (Great burnet)
Gorgeous perennial that flowers during summer and into autumn with a mass of deep burgundy fluffy flowers on long stems. A favourite plant of the New Perennial/New Naturalism designers. Does need moist soils in our hot summers to flower continuously so place somewhere reticulated or near to a hose! Deadhead as needed or early winter to tidy. 0.9mH x 0.3mW. Full sun to part shade.
