Hair grass (eleocharis acicularis), also known as Needle spike-rush, is an attractive dense-growing British native grass and is an excellent oxygenator if grown under water, where it will grow to around 15cm high. It is also happy in shallow water but will be much shorter. It provides an excellent under water habitat for amphibians and other pond life.
Eleocharis helodes (growing in marshes) and charis (grace); acicularis needle like stems
