Go Back Variegated Sweet Flag Ornamental Grass

Acorus Calamus 'Variegatus'
Deer Resistant Icon

Plant Type: Grasses

Long, up to 1 inch wide leaves stand tall to display their striking variegation of bright green and creamy yellow. When crushed, they emit a delicious tangerine scent. This grass is simply stunning and is sure to catch your eye. It is especially beautiful when back lit by the early morning or late afternoon sun.  Sweet Flag gets its name from the sweetly scented essential oil,calamus, which is present in all parts of the plant.  Native to bogs, shallow ponds, and marshes, this plant will grow in shallow water. It also looks great in tubs, pots, water gardens, and along the pond's edge. This grass is not invasive. Acorus is not a true grass. It is a member of the genus Araceae, which is the arum or philodendron family.


Growing & Maintenance Tips:

Acorus prefers to grow in fertile, constantly moist, acidic soil.However, it will tolerate a wide range of conditions as long as moisture is constantly available. It will even grow in standing water up to 5" deep. If the soil dries out, the tips of the leaf blades will brown and be unsightly. In most parts of the country Acorus can be grown in full sun. In warmer inland areas, however, some shade should be provided. Propagate by division only.
