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 pruning hard and dividing any dense plant cushions. Plant the cut rootstock at 5 cm intervals. The first submerged blades will appear after just a few days.
