Cyperus helferi makes a beautiful mid-ground or background plant with its long leaves that flow with the water movement, though its small root system means it cannot tolerate a strong current. Transferring this plant can cause some leaf melt. Cyperus helferi can grow to a height of 40cm and it's leaves will drift across the top of the tank. Perfect for hiding equipment at the back, this plant can thrive in larger tanks. For smaller tanks, regular trimming will be required.
