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.
