Ideal for wet areas, Acorus gramineus 'Ogon' (Golden Variegated Sweet Flag) is a semi-evergreen herbaceous perennial forming an attractive tuft of gracefully arching, narrow, sword-shaped, golden-yellow leaves adorned with olive green stripes. The foliage is sweetly fragrant when bruised and evergreen in mild winter areas. From spring to early summer, it bears inconspicuous yellow-green flowers that give way to tiny, reddish berries. A great choice for naturalizing, Golden Variegated Sweet Flag is quite versatile in the garden and terrific in mixed containers. It also makes a useful aquarium plant.
