Great Burnet (Sanguisorba officinalis) is a perennial with distinctive red/burgundy tightly packed flower clusters on tall, leafless stalks. It flowers from June – September and requires damp ground with full sun, but can grow on drier soils. It can reach just under a metre tall. The pinnate leaves of Great Burnet do not smell of cucumber – as its relative Salad Burnet does – when crushed. The leaves look green from above and grey from below.
