Acorus calamus
Calamus (sweet flag) is a wetland perennial grown for its fragrant, sword-like foliage with a long history of medicinal and aromatic use. It thrives in boggy, waterlogged soil or at the margins of ponds and streams in sun to partial shade. This easy-care plant requires little attention beyond keeping its roots consistently wet and dividing clumps every few years to maintain vigor.
