Plant Common Name

Miniature Papyrus

General Description

African in origin, miniature papyrus is a super compact sedge adapted to moist ground and riversides. This evergreen tender perennial is best suited to containers and lowland gardens, and even though it's only hardy to zone 9 it can be grown as an annual in areas with cold winters.

This compact papyrus forms bunches of pinwheel-like floral heads and foliage. The arching stems are topped with fine green bracts. When weather is warm and accommodating, green and reddish brown spikelets of flowers appear among the bracts. These are wind pollinated and followed by brownish seeds. This papyrus is not yet known to self-sow or spread aggressively, but gardeners should still treat it with caution until they know how it will behave in their growing area.

Grow dwarf papyrus in a rich, fertile soil that is either moist or fully saturated with very shallow water that does not cover the crown. Full to partial sun are acceptable for good growth. Where hardy, it can be planted in the ground or in containers with moist soil. Elsewhere, it can be planted as a tender perennial or brought indoors when outdoor temperatures become too cold. Trim back dead or dying stems in late fall and remove any fallen debris that may have collected amid the living stems.
