Isolepis cernua var. cernua | slender clubrush, fiber-optic grass
A compact, tufted grass forming a neat clump of bright green, radiating foliage, topped with distinctive silver flower heads. Its fine texture and vivid colour make it a striking accent plant, particularly where close viewing is possible. Well suited to planting beside ponds and streams, around outdoor living areas, mass planted on banks, or grown in containers. Naturally associated with damp sites and dune margins, it prefers moist conditions and can spread slowly by short creeping growth, creating soft, luminous patches in the landscape.

The plant's common name fibre optic grass describes the small, white or silver flower heads that emerge at the tips of its fine, hair-like stems. When mature, the stems gracefully arch and droop, resembling a miniature, bright green spray of fiber optic threads or "fairy lights".
