Cyperus helferi


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.

The genus Cyperus (papyrus sedges) comprises about 900 species, among them the African papyrus (Cyperus papyrus) and the well-known houseplant C. alternifolius. However, there are only a few Cyperus species that can truly grow submersed, among them Cyperus helferi. This aquatic plant is found submersed as well as emersed in Thailand, in stagnant and slow-flowing waters.

This Cyperus species is not very difficult in cultivation, given that it survives it rather long adaptation period. It grows best under lots of light (0.5 – 1 watt per litre). There is no need to fertilise with CO2, however, if CO2 is added it enhances growth significantly. This plant likes its water on the cooler side, thus a temperature of 26 °C should not be exceeded for optimal growth. A good supply of nitrate, phosphate, potassium and micronutrients enhance growth and further a healthy look.
