Golden Variegated Sweet Flag creates a beautiful mat of bright green and gold and that’s plenty of color to jazz up shady spots or moist, sunny areas. Acorus gramineus ‘Ogon’ grows in a tufted mound with grasslike, narrow blades. Plant it in moist areas to create a dense ground cover, or use it to accent water features or ponds. Golden Variegated Sweet Flag spreads very slowly by rhizomes. As with others in the Acorus genus, its leaves emit a fresh citrus scent when pinched or bruised.
This plant performs best with constant moisture (not standing water). It will adapt to average moisture, but prolonged dry spells may cause leaf tips to brown. The foliage color and intensity of variegation depend on light exposure. Brighter light lends more golden color, while deeper shade highlights green. Variegation is strongest in moderate shade.
