Formerly known as Cyperus alternifolia, this excellent specimen plant will grace any pond with its tall, sturdy stems crowned with attractive sprays of umbrella-like leaves and delicate feathery seeds. It is by far the most ornamental member of the Cyperus family, and is evergreen until the first frosts come. It has an exotic foreign look - it is a relative of the Papyrus grass - and this makes a useful contrast with other pond plants and lifts the look of the pond. It is very slightly frost tender so the crown of the plant should remain below the water during winter to protect it from any possible ice damage. Hence we have recommended a planting depth of 3 - 4 inches. In frost-free areas it could be planted as shallow as you wish.
If designing a planting scheme, we recommend approximately 2 Cyperus involucratus plants per square foot of ground, or 1 plant per linear foot of pond edge. Read more here on how to pot and care for your plant.
