Graceful Grasses® Fiber Optic Grass Scirpus

Graceful Grasses® Fiber Optic Grass is a mounded, grass-like perennial in warm climates and an annual where winter cold prevents it from persisting. Fine green leaves carry small white, fiber-like flower tips; the official Proven Winners profile gives a mature size of 10–14 inches high and wide and identifies this selection as *Isolepis cernua* ([Proven Winners plant profile](https://www.provenwinners.com/plants/isolepis-scirpus/graceful-grasses-fiber-optic-grass-isolepis-scirpus-cernua)). ## Seasonal Interest Proven Winners lists spring and summer flowering, with green foliage and small white tips adding texture to containers and border edges. This selection is sold as part of the Graceful Grasses line. Its exact plant page also provides the catalog’s cultivar-specific height, spread, exposure, and hardiness range. ## Growing Conditions Grow in part sun to full sun, keeping moisture steady; shade is useful where afternoon heat dries containers quickly. The plant tolerates wet conditions and works in damp containers, rain gardens, or pond margins, but do not confuse its 10–12-inch spacing recommendation with its larger 10–14-inch mature spread. Proven Winners lists USDA zones 8a–10b and describes it as an annual in colder areas; survival and evergreen appearance depend on winter temperatures. ## Maintenance Keep container soil evenly moist and trim away brown growth when it appears. In warm areas where plants persist, divide in spring and handle the fine roots gently. In colder climates, treat it as a seasonal annual or move a container to a protected space before freezing weather.
