Slender Club Rush
Also called the 'Fibre optic plant', this bright green rush with slender evergreen leaves grows in attractive clumps. A native British plant that produces masses of tiny white flowers on emergent foliage. The submerged green shoots can assist with oxygenation of the pond water. It provides good habitat for wildlife. Plant in a medium container using aquatic soil with a good covering of pea gravel to prevent fish from uprooting the plants. This versatile grass can also be planted in a moist situation in the garden where it's attractive and unusual foliage contrasts well with other plants.
