They are annual or perennial plants, mostly aquatic and growing in still or slow-moving water up to 0.5 m deep. The species vary greatly in size, with small species only 5 cm tall, while others can reach 5 m in height. Common names include papyrus sedges, flatsedges, nutsedges, umbrella-sedges and galingales. The stems are circular in cross-section in some, triangular in others, usually leafless for most of their length, with the slender grass-like leaves at the base of the plant, and in a whorl at the apex of the flowering stems. The flowers are greenish and wind-pollinated; they are produced in clusters among the apical leaves. The seed is a small nutlet
Apply a half dilution of fertilizer once per month during the growing season and suspend in winter. Watch for splashing on the leaves, as fungal diseases can spread in this manner. Propagating this plant is easy. Just take a 4- to 6-inch cutting and suspend it upside down in water. Roots will emerge and you can place the new plant in soil. Divide your houseplant every three years. Remove the plant from the pot and cut out the outside growth. Save and pot up this newer growth and discard the old central older plant.
