Native to Africa, Cyperus papyrus, commonly called papyrus, is a tall clump-forming, tender perennial sedge that, in frost-free areas, will grow up to 15’ tall. In St. Louis gardens, stems will grow much shorter (to 5-8’ tall). It features a grass-like clump of triangular green stems that rise up from thick, woody rhizomes. Each stem is topped by an umbellate inflorescence of 100+ narrow arching thread-like rays (4-12” long). Greenish-brown flower clusters appear at the ends of the rays. Flowers give way to brown, nut-like fruits. KING TUT is a dwarf cultivar that typically grows 4-5’ tall.
No serious insect or disease problems. Not winter hardy to St. Louis area.
