Stachys palustris, commonly known as Marsh Woundwort, is a perennial herb that thrives in the damp environments of Europe and Asia, specifically in wet meadows, marshes, and along stream banks. It typically grows up to 31 inches tall and features square stems with opposite leaves. The plant blooms from July to September, producing whorls of purplish-red flowers that are highly attractive to bumblebees and other pollinators. The flowers are modest in size but can be quite showy due to their dense clusters.

Marsh Woundwort is valued for its historical medicinal properties, traditionally used to treat wounds and various ailments. In cultivation, it can serve as a water garden or bog garden plant, providing both aesthetic and ecological benefits. It prefers consistently moist to wet soils and can tolerate a range of light conditions from full sun to part shade. However, gardeners should be aware of its potential to spread aggressively via its hollow, tuberous roots. In North America, where it has been introduced, it can become a persistent weed, and its dry, floating fruit capsules aid in its dispersal.CC BY-SA 4.0
