Heteranthera zosterifolia “star grass” from South America is an especially beautiful aquarium plant. It ramifies well, which results in dense bushy plant groups after only a short time. Under strong lights Heteranthera zosterifolia “star grass” grows fast and needs frequent trimming to ensure that the lower leaves are still reached by the light. It often throws water roots on the stems. On shoots floating on the water surface, small blue flowers will grow above the waterline.
In the hobby, H. zosterifolia has been established for many years as a decorative plant for Dutch style aquaria as well as nature aquaria. Here it is used as contrasting plant in the fore-, the middle- and the background by simply cutting it to the desired height.
Known as star grass by vernacular name, this plant is a great water quality indicator. A lack of nitrogen (in the form of NO3) lets the leaves become transparent before they wilt. A lack of phosphorous (in the form of PO4) changes the plant’s bright green into a darker hue.
H. zosterifolia is a relatively undemanding plant and grows well at medium light intensities without additional CO2 fertlisation.
Just like fish, living plants do best when they are kept in an aquarium that best suits their needs. Selecting live plants that share common water conditions will minimize problems and make it easier for you to maintain and keep your aquarium in tip top shape. We want your plant to thrive and become a favorite part of your tank. Do research before purchasing and be sure to choose plants that are suitable for your aquarium so you will get the most out of your new addition.
