A native wetland perennial with square stems and purple-pink flowers arranged in spiky whorls. It thrives in boggy or marshy conditions and attracts pollinators.

Why grow it

Marsh woundwort offers reliable pollinator attraction in wet sites where many ornamental perennials struggle. Unlike some wetland species that require standing water year-round, it tolerates seasonal fluctuations typical of marshy margins and poorly drained soil. Its native status makes it a functional choice for rain gardens and constructed wetlands where it can spread modestly to stabilize banks.

Watch out for

In consistently moist conditions, this species can self-seed readily and expand beyond initial planting boundaries, so consider containment if space is limited. Foliage may decline or thin in extended drought, though established plants typically recover with autumn moisture.
