Variegated Sweet Flag Acorus gramineus 'Variegatus' (v)
ABOUT
The Dwarf sedge 'Variegatus' is a striking ornamental grass-like perennial with a lush appearance. This variegated form is particularly eye-catching due to its slender, sword-shaped leaves that gracefully arch and display a unique color pattern. Each leaf is a tapestry of green and creamy white or pale yellow longitudinal stripes, giving the foliage a vibrant and refreshing look. The blend of green and cream stripes runs the full length of the leaves, presenting a neat and tidy variegated effect. The leaves emerge from slowly spreading rhizomes, forming dense tufts or clumps that create a textured ground cover. The overall look of the Dwarf sedge 'Variegatus' is one that can brighten up shady garden areas with its vivid foliage, which also has a slightly glossy finish, adding a bit of sheen to its appearance. Its grass-like strands provide a contrast in form to other garden plants, making it a valuable addition to landscape designs, rock gardens, pond edges, and even as an accent in container plantings. During the growing season, tiny, inconspicuous flowers may appear on the Dwarf sedge 'Variegatus', but they are often overlooked due to being hidden within the foliage and not being as showy as the leaves themselves. The focus with this plant is truly on the lush tapestry of variegated foliage that creates a visual interest throughout the year.

WaterThe Variegated Sweet Flag requires consistently moist soil and should be watered thoroughly when the top inch of the soil feels dry to the touch. Depending on the environmental conditions, this may mean watering the plant every week with approximately 1 to 2 gallons of water. It is important to avoid letting the soil dry out completely, as well as to prevent water from standing in the container, which can lead to root rot. During the growing season in spring and summer, the Variegated Sweet Flag may need more frequent watering to maintain the proper moisture levels.
LightVariegated Sweet Flag thrives in partial shade to full sun. The ideal location would receive morning sunlight and afternoon shade, or filtered light throughout the day. Direct afternoon sunlight should be avoided as it can cause the foliage to scorch. A spot that offers bright, indirect light will help maintain the vibrant variegation of the leaves.
TemperatureVariegated Sweet Flag prefers temperatures between 50°F and 80°F. It can tolerate temperatures as low as 30°F, but prolonged exposure to cold can damage the plant. The ideal temperature range encourages healthy growth while protecting the plant from extreme heat or frost, which can be detrimental.
PruningPruning the Variegated Sweet Flag is primarily for aesthetic purposes, to remove any yellow or damaged leaves and to maintain a tidy appearance. Pruning can be done any time of the year as needed, but it's best to do the majority of trimming in early spring before new growth begins. There's no need for rigorous pruning; simply cut back any unsightly or old foliage to the base.
CleaningAs needed
SoilThe Sweet Flag prefers a soil mix that is rich in organic matter, consistently moist, and well-draining, ideally with a pH of 5.5 to 6.5. An ideal soil mix can be created with equal parts of garden loam, peat moss, and sand to ensure proper moisture retention and drainage.
RepottingSweet Flag should be repotted every 2 to 3 years during spring. When repotting, divide the rhizomes to propagate new plants and refresh the soil to provide nutrients for healthy growth.
Humidity & MistingSweet Flag thrives in high humidity conditions. Maintaining a humidity level around 70-90% is ideal for this plant, but it can tolerate lower humidity levels without significant harm as long as soil moisture is adequate.
Suitable locationsIndoor
Place Sweet Flag in bright, indirect light with moist soil.
Outdoor

Life cycleAcorus gramineus 'Variegatus', commonly known as Variegated Sweet Flag, begins its life cycle when seeds or rhizomes are planted in moist, fertile soil, often along the edges of ponds or streams. Germination of the seeds or growth from rhizomes develops into a clump of sword-like, variegated green and white foliage that thrives in full to partial sunlight. As the plant matures, it spreads through rhizomatous growth, forming dense colonies that can outcompete weeds. During spring or early summer, the Variegated Sweet Flag produces inconspicuous, greenish-yellow spadices that are often hidden among the leaves. After the flowering stage, the plant does not typically produce viable seeds; thus, reproduction mainly occurs vegetatively through the division of rhizomes. Throughout its perennial lifecycle, the plant will continue to grow and spread, requiring periodic division every few years to manage growth and maintain vigor.
PropogationPropogation time
Spring to Summer
For Acorus gramineus 'Variegatus', commonly known as variegated sweet flag, the most popular method of propagation is by division. This is best done in the spring, as the plant emerges from dormancy and begins to show new growth. To propagate by division, carefully dig around the plant to lift it from the ground, making sure to keep a good amount of soil around the roots. Gently separate the plant into smaller sections, each with a portion of the root system intact. These divisions can then be immediately replanted in moist, well-draining soil, either in a pot with a diameter of at least 6 inches (about 15 centimeters) or directly into the ground in a location that matches the plant's light and moisture requirements. The divisions should be watered thoroughly after planting to help establish the new plants.
