Cyperus helferi, sometimes just called cyperus, is a grass-like rosette plant from Thailand that grows fully submerged. It sends out long, narrow ribbon leaves, roughly 20 to 35cm tall from a rosette 15 to 25cm wide, that arch over and sway in the current. It sits well in the midground to background where those leaves have room to fan out.Give it a decent amount of light and it grows into a fountain of movement, and it looks its best in a tank with good water flow so the leaves drift back and forth. A little CO2 helps it grow in and keep that fresh green colour. It is a slower grower, so it holds its shape and stays tidy once it has settled in.Care at a glance Placement: Midground Lighting: Medium CO2: Medium Growth rate: Slow Difficulty: Intermediate Colour: Green Not all plants are equal. All our plants are harvested fresh, algae free and in great health. The conversion to submerged form starts in our grow-out tanks, which maximises your success once it settles into your aquarium.Submerged: A plant grown completely below the tank's waterline.Emersed: A plant with growth above the tank's waterline, such as leaves, stems and flowers.
