Ornamental Grass, Acorus gramineus 'Sweet Flag'
Item F21OG360

Acorus gramineus 'Sweet Flag' has golden variegated, butter-yellow sword-like blades to add contrast in the landscape. This is a low-growing perennial. 'Sweet Flag' is small, beautiful and easy to grow. It has survived even the worst winters. It’s excellent for brightening the edges of ponds or water gardens. Rich golden yellow blades provide colorful accents, even in lightly shaded areas. Crushed foliage emits delightful scent. Evergreen.

The thin iris-like foliage, variegated longitudinally with bright butter yellow stripes, forms in fan-like clusters to 6-14 inches tall. The inconspicuous flowers are 2-8 inches long. This plant spreads by rhizomes but is not invasive. It is an excellent foliage plant for the waterside edge or shallow ponds. Useful massed or as an accent; use it to lighten a dark area of a pond.




Size: #1 · Hardiness: Zones 4-11

Common: Ornamental Grass · Botanical: Acorus gramineus 'Sweet Flag' · Family: Poaceae

Height: 6-14" · Spacing: 4-6" wide

Bloomtime: The flowers are inconspicuous and the plants are grown mainly for their foliage.

Exposure: Full Sun to Partial Shade · Flower: Inconspicuous · Foliage: Butter-Yellow to Green

Care Information: Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. For a neat appearance, remove old foliage before new leaves emerge. Divide clumps every 2 to 3 years in early spring.

Noteworthy Characteristics: Deer Resistant, Dwarf Plant. Japanese sweet flag is used along pond margins and at the edges of water gardens. It's a great foliage plant for shallow water and marshy areas. It spreads aggressively by rhizomes and will eventually produce a seamless turf, making a beautiful ground-cover for the front of a bog garden. When walked upon, it releases a fragrance reminiscent of cinnamon. If you don't want a solid stand of Japanese sweet flag, grow it in submerged containers so it can't spread. In Japan, the smaller cultivars often are grown in shallow water in containers indoors.

Ornamental Grasses are gaining in popularity all over the U.S. due to their undemanding nature and long lasting, year round beauty. There is nothing that adds such interesting forms, textures and movement to a garden, than with this diverse plant group. They can be planted along banks of ponds, incorporated into perennial gardens, grouped together, utilized as a ground cover along walkways, paths or on steep banks. They aren't fussy about soil requirements, are drought tolerant as well as insect and disease resistant.

Uses: Acorus 'Sweet Flag' great for containers, edging or as a ground-cover. It is often used for water gardens, along streams or ponds or in moist open woodland gardens. Acorus is also effective in rock gardens or border fronts or as small landscape accents as long as the soil moisture requirements can be met. Excellent for erosion control along the banks of streams and ponds.

Pests: No serious insect or disease problems. Deer Resistant Plant.

Planting instructions: Dig a hole large enough to hold the roots. Fill the hole with water and position the plant so the crown (where the root meets the stem) is just slightly below the soil line. Fill the hole with soil and water again. A slow release fertilizer may be used each spring, though it’s not necessary.
