Umbrella Sedge - Plant
Umbrella sedges, ornamental grasses belonging to the Cyperaceae family, are herbaceous perennials commonly grown in backyard containers and water gardens. These aquatic plants flourish in the moist wetland soil at creeks and pond edges, and can help hold wet soil together, especially around water sources with sloping banks.
Umbrella sedges come in a variety of types, including a popular dwarf variety (Cyperus albostriatus) and the larger Cyperus involucratus. They tend to grow quickly, often overpowering their original planting location, and require some yearly trimming.
Common name: Umbrella Sedge
Bloom time: Early July through late August
Height: 6-15 inches.
Difficulty level: easy
Planting & Care
Umbrella sedge can grow in standing moisture or in ponds as well as in perennial beds if watered regularly. It also is suitable for container growing, and you can grow it as a houseplant in cold winter areas. If you have limited garden space, plant it in a container before adding it to ponds or gardens to restrain its root growth.
Umbrella sedge can become invasive under the right conditions either by spreading its seeds or by forming clumps. When the clumps get too large or root-bound, unpot them or dig them up to divide them.
