Dwarf Umbrella Grass
Ornamental grasses and grasslike plants, Perennials, Aquatic
These African natives are sedges–grasslike plants distinguished from true grasses by three-angled, solid stems and very different flowering parts. Valued for striking form, silhouette, shadow pattern.
Most cyperus grow in rich, moist soil or with roots submerged in water. Kept plants groomed by removing dead or broken stems; divided and replanted vigorous plants when the clump becomes too large, saving smaller, outside divisions and discarding the overgrown centers. Beyond their hardiness range, pot up divisions and keep them over the winter as houseplants.Cyperus albostriatus
A clump of upright 1 1/2-ft.-tall stems is topped by a tuft of broad leaves and, in late summer, loose starbursts of tiny greenish-yellow flowers. Overall appearance is lush and soft. Vigorous, invasive plant; best used in contained space.
