Haspan Flatsedge, Dwarf Papyrus Sedge, Dwarf Sedge, Haspan Flat Sedge, Sharp Edge Sedge


Cyperus haspan (Dwarf Papyrus) is a rhizomatous aquatic perennial forming a tuft of upright, three-angled, green stems. Atop the stem rests a rounded spiked umbel of yellow-green florets that turn bronze in late summer. Providing year-round interest, this member of the sedge family is a charming addition to the water garden thanks to its delicate evergreen appearance and fireworks-like flower heads. While papyrus plants are perennials in warm climates, many gardeners use them as if they were annuals in colder climates. In ponds, plant in a basket as it may be invasive.

  • Grows up to 12-30 in. tall (30-75 cm) and 24 in. wide (60 cm).
  • Performs best in full sun or partial shade in wet soils. While it thrives in consistently moist garden soil, it can also be planted in standing water to 3-5 in. deep (7-12 cm).
  • This architectural grass is highly versatile. It may be grown at the edge of a pond or water garden, in boggy areas, in shallow water and in containers.
  • Virtually disease and pest free
  • Cut back dead stems and culms in fall.
  • Propagated by division or by rooted plantlets that form when the flower heads touch the water or by cutting off the flower head and floating it upside down in water.
  • Native to the Southeastern United States, the West Indies, Mexico, Central America, South America, and the Old World.
