Characteristics: Cyperus is not hardy enough to survive winters with freezing temperatures and it is not a candidate to overwinter inside. It is a very fast grower and will quickly grow to impressive size when replanted in the spring.
The plant can be planted in pots, along the waters edge of a pond, or even in a pond. The crown of the plant should never be covered in water and in fact both of these varieties can thrive in water as shallow as a few inches. The purpose is to keep the bulk of the soil or root mass wet. The root ball can be submerged but it isn't necessary. If the plant is put into a pot I would suggest plugging the hole or holes in the bottom of the pot to keep as much water as possible in the pot
