Acorus calamus ‘Variegatus’
Sweet flag
Natural sweet flag is believed to originate from India. It is now found through much of Europe and Asia, as well as North America. This cultivar has green and white leaves instead of green leaves, and is not found in the wild. The name sweet flag is probably due to an old practice of simmering the roots to prepare a candy; it may also be because the foliage and root stalks have a pleasant aromatic fragrance. The American poet Walt Whitman was enamored with sweet flag, devoting 39 poems to it.

Fruits: Tiny fleshy berries.
