Japanese Sedge

About this plant

Known for its exceptionally fine, cascading foliage, Carex oshimensis 'Feather Falls' creates a sophisticated, airy presence wherever it's planted. Its narrow, bright green leaves feature delicate creamy-white margins, forming attractive mounds that sway gently in the breeze. This versatile ornamental grass is excellent for mass plantings, defining borders, or a graceful spill-over element in containers and hanging baskets. It offers year-round interest, maintaining its beautiful form and color even through winter in milder climates. A perfect choice for adding subtle movement and soft texture to foundations, woodland gardens, or alongside water features, 'Feather Falls' is a low-maintenance gem that brings continuous visual appeal.

Installation timing

When we're in season, outside of the winter months, our goal is to get your plants installed within about two weeks. That window gives us enough time to secure your plants from our supplier and find a spot on the schedule. Throughout the process we stay in touch through notifications and your existing client portal on the main A Cut Above website, which is separate from this landscaping plants shop.

Care & maintenance

Requires minimal care once established. Trim back any browning or dead foliage in late winter before new growth emerges. Does not typically require division. Very resistant to pests and diseases.

Watering suggestions

Proper watering is the single most important factor in your plant's survival after installation. Newly installed plants have a limited root system and rely on you for consistent moisture while they establish.

• First 2 weeks: Water deeply every day (or every other day in cooler, wet weather), soaking the root ball and surrounding soil.
• Weeks 3–12: Water deeply 2–3 times per week, adjusting for rain, heat, and soil drainage.
• After establishment: Water deeply about once a week during the growing season, and more often in extreme heat or drought.
• How to check: Stick a finger 2–3 inches into the soil near the roots — if it's dry, it's time to water. Deep, less-frequent watering encourages strong roots; shallow daily sprinkles do not.
• Avoid: Overwatering (soggy, waterlogged soil) is just as harmful as underwatering and can drown roots.

Watering needs vary by plant, season, soil, and exposure. Because proper watering is the customer's responsibility after installation, please make sure you understand and can follow these suggestions before ordering.

Good to know: plants and trees purchased from and installed by A Cut Above include a one-year limited warranty from the date of installation. Because plant survival depends heavily on proper watering and care after installation, losses caused by improper care, neglect, animal or chemical damage, or extreme weather are not covered, and we must be given the chance to inspect a struggling plant before it's removed or replaced. Coverage is one replacement per plant. Read our warranty info.
