Family:Cyperaceae

This plant thrives in either full sun or partial shade and can be utilized in water gardens or as a houseplant by placing it in a container filled with water. It requires consistent moisture or can be grown in standing water, favoring nutrient-rich soil. Exposure to direct sunlight and wind may cause the bracts to turn brown. It is best to plant it in a pot ranging from 2 to 5 gallons, ensuring that the crown is submerged under 1 to 6 inches of water.

Identification Tips:

This rhizomatous herb can reach heights of up to 3 feet, featuring multiple stems that spread out. Its inflorescence is not particularly decorative, and the scapes often grow so long that they may bend over and take root, potentially needing support. It thrives in standing water and is well-suited for placement in or near water features.

The plant prefers bright light, consistently wet soil, and medium to high humidity levels. It is easy to propagate but may encounter pest issues.
