General Culture:
Grow in wet, boggy soils in full sun to part shade. Best in part shade. Grow in containers at the margins of water gardens, pools or ponds. Grows well in both standing water (up to 12? and in boggy soils. In the St. Louis area, these plants are tender perennials that must be brought indoors in fall before first frost for overwintering in a large sunroom or greenhouse. When overwintering, place container in a large saucer filled with water. In USDA Zones 9 and 10, these plants are grown outside year-round and will freely self-seed in optimum growing conditions.
Noteworthy Characteristics:
Native to Africa, 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 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. In ancient Egypt, the stems of this plant (considered by some authorities to be the bulrush of the Bible) were used to make a paper-like writing material also called papyrus. A dwarf version of this plant, designated as C. p. 慛anus?or C. profiler, typically grows to only 2-3?tall.
Problems:
No serious insect or disease problems. Not winter hardy to St. Louis area.
Uses:
Tall, graceful accent for water gardens, bogs or pond/stream peripheries. Patio containers/tubs.
