The needle rush Eleocharis acicularis is found all over the world. It is a particularly lithe, grass-like plant for the foreground. It prefers cooler water, but does grow perfectly well at higher temperatures. Side runners shoot out, over time, to produce a thick carpet of plants. When bedding in plants cultivated in the emersed state, we recommend cutting them back severely and dividing any dense plantings. Plant the cut rootstock at 5 cm intervals. The first submersed blades will appear after just a few days.
