Acorus calamus, or Sweet Flag, is a tall perennial with scented, sword-like leaves and even stronger scented rhizomes. This plant grows with “wet feet,” often found along the edges of ponds, lakes and rivers with irises. Sweet Flag has been use medicinally, chewing the rhizome for fresh breath and digestive aid. At one point, Sweet Flag or Calamus was used as a substitute for ginger, cinnamon and nutmeg, but the FDA now prohibits its use in food products. The plant was favored by Walt Whitman, who wrote 39 Calamus poems in his renowned poetry collection Leaves of Grass.
