Aquatic

A semi-evergreen, slow-growing, compact aquatic plant with short stems and narrow, pale green leaves which form rosettes and send runners out to create a carpet effect. If not submerged, a very small, four-petalled single white flower emerges from the centre of the rosette from May to August. It generally copes well in shade, and can be found in ponds, lakes and slow-moving streams. It is also suitable for terrariums and aquariums
