Cyperus-species are widespread all over the tropics, but only a few of them are good underwater plants. Cyperus helferi from Thailand is the first Cyperus-species used in aquariums, 20-35 cm tall and a roset from 15-25 cm wide. It requires a relatively large amount of light, and CO2 addition is recommended to promote growth. In aquariums with good water flow the plant sways beautifully in the current.

Propagation is similar to other aquatic stem plants and can be gently trimmed and replanted into aquarium soil. Frequent trimming should be performed to encourage and produce bush-like growth.

Notes:

• Do not make drastic changes to the aquarium. Unstable parameters will result in melt and rotting of the aquarium plant.
• Aponogeton grows fairly large making this aquarium plant suitable for larger planted aquariums.
• If received in a pot, please remove all rock wool from the roots. Where possible we try and ship without pots or rockwool. Due to them being non-biodegradable we prefer to propagate in an environmentally conscious way.
• CO2 will generally yield better growth rates.
• Stables water conditions are a must, changes should occur over a period of time in order to reduce chances of melting etc.
