Bistorta officinalis subsp. officinalis

Common bistort is a hardy perennial that thrives in moist, humus-rich soil in partial shade, making it ideal for woodland edges or damp border plantings. Its edible leaves can be harvested in spring and it has a long history of medicinal use in European herbal traditions. Once established it requires minimal care — simply keep the soil moist and divide clumps every few years to maintain vigor.
