Genus guide
Cyperus — 6 species
Part of the Ornamental grasses & bamboo family (Poaceae & allies)
Cyperus is a large sedge genus best known for bold, umbrella-like ray leaves on tall, upright stems — Dwarf Papyrus and Cyperus papyrus are the showiest, while Cyperus alternifolius (umbrella grass) is the most popular houseplant form. All thrive in bright indirect to full sun and demand consistently wet soil; many tolerate standing water, making them ideal for bog or pond margins. Toxicity varies across the genus: some species are considered non-toxic to cats and dogs while others may cause mild reactions, so check each species before buying.

Cyperus — frequently asked questions
Are Cyperus plants toxic to cats and dogs?
Most Cyperus are not pet-safe. Of the 6 Cyperus species in the Growli library, 5 (83%) carry a toxic or mildly-toxic ASPCA classification and 1 are pet-safe. Always confirm the exact species on its pet-safety page before trusting it around cats or dogs.
How much light do Cyperus plants need?
Most Cyperus do best in direct sun. If yours stretches toward the window or loses its variegation it wants more light; scorched or bleached leaves mean it is getting too much direct sun.
