Cyperus is a large genus of plants in the family Cyperaceae, commonly known as sedges. These plants are found throughout the world, with a concentration of species in tropical and subtropical regions.
Cyperus plants typically have triangular stems with grass-like leaves that are arranged in a spiral pattern. The flowers are usually small and inconspicuous, and they are often arranged in dense clusters or spikes. Some species of Cyperus are aquatic or semi-aquatic, while others are adapted to drier environments.
In the aquarium hobby, Cyperus is a popular genus of aquatic and semi-aquatic plants known for their striking appearance and ease of care. They are often used as background or accent plants, and their tall, grass-like leaves can add a sense of height and texture to the aquarium. Cyperus plants prefer moderate to high light intensity and nutrient-rich water. They can be planted in the substrate or attached to rocks or wood using fishing line or aquarium-safe glue. Some popular species of Cyperus in the aquarium hobby include Cyperus helferi and Cyperus alternifolius.
