Mop-headed sedge. This whimsical sedge has become a favorite in our garden, where it acts as a dense, fine-textured, evergreen groundcover to 8” high. The rich green foliage forms rounded mounds (much like the hair cuts of those famous British invaders) that provide lush fill between stepping stones, along paths and in the foreground of perennial or grass borders. Healthy plants tolerate light foot traffic and may be used as a lawn substitute in small areas. One of the best low-growing sedges, this one is ideal for moist, rich soils in partial shade. Plants in our garden have remained bright green with only occasional water. Hardy to 0F. Garden origin.
