About the Plant

From the Acoraceae family, Acorus calamus is a tall perennial wetland monocot with scented leaves and more strongly scented rhizomes. Commonly known as sweet flag, sweet root, its Sanskrit name is vacha. While it is thought to have originated in Central Asia or India in the common areas that surround the Himalayas, this very decorative plant now grows wild in all temperate zones of Europe, Asia and America, along brooks, rivers, lakes, etc. It was introduced to N. America by early European settlers who grew it for medicinal purposes. The muskrat appears to be an animal responsible for its profliferation because they eat the rhizomes and collect them for future use, and under proper conditions, the pieces may produce new roots. Because the rhizomes can be dried without a substantial loss of essential oil provided they are kept unpeeled, distillation can take place in many countries far from the country of plant origin. The plant has branched, aromatic rhizomes with sword-like leaves that are sharp pointed with a ridged midrib running the entire length.. In late spring, green flowers appear in 2 to 4 long spadices below the leaf tips. Flowers eventually give way to small berries. Calamus grows in both temperate and sub-temperate areas of the globe.

The blue flag, also called poison flag, has similar leaves to those of calamus. Blue flag rhizomes can be dangerously toxic, so if you are wildcrafting this plant, make sure you can tell the difference.
