Acorus General Information

Sweetflag grows well in both boggy and moist garden soils. Naturalizes politely by spreading rhizomes. Native to Japan-neat clumping habit with grass-like foliage. Ornamental Grasses are restricted from Idaho and Oregon. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Acorus Plant Care

For a neat appearance, remove old foliage before new leaves emerge. Divide clumps every 2 to 3 years in early spring. Plant divisions in pots until well-rooted, then transplant to a permanent location. Requires moist, acidic soil. An excellent choice for the rain garden, stream or pond margins, bogs or moist woodland gardens.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!
