This cultivar has good silvery blue foliage, but it is not too different from the mother species of the Creeping Sedge. The mother species has a native range from southern Ontario & Quebed through Maine into Florida to Arkansas up into Minnesota to USDA Zone 4, growing in rich woods, along stream banks, and in swamp margins. It slowly colonizes by rhizomes. Its tiny yellow flowers in spikes are not ornamental. It is sold by some native plant nurseries as North Creek in southeast Pennsylvania and New Moon in southern New Jersey, and by some larger, diverse conventional nurseries. So far, I've only seen it in the Philadelphia Flower Show in March 2018 in a Delaware Valley watershed display.
