The grassy swordlike leaves of the two species of Acorus thrive at the edges of ponds in shallow water or bogs. Flowers are interesting, but not showy, yet are often mistaken for Irises. They spread slowly by fragrant underground rhizomes. Excellent in moist or waterlogged situations, best in fertile soils in full or part sun.
Shorter and slower growing than the species. Grows white-striped leaves that add interest to small water gardens and ponds, especially amid water lilies and water hyacinths.
