Sweet flag is named for its sweet-smelling leaves when they are broken. This fragrance becomes even more pungent when the leaves are hung and dried out.
The grassy leaves of this water-loving perennial form an excellent vertical accent for a water garden. An especially attractive form, 'Variegatus,' has dark green leaves marked with cream. Its popular relative, A. calamus, is taller and less bushy.
