Carex oshimensis 'Evergold' (Variegated Japanese Sedge) - A clumping forming evergreen sedge to 12 to16 inches tall by about 20 inches wide with arching narrow leaves that have a creamy yellow central stripe and dark green margins. In later winter appear the brownish insignificant flowers that rise not much above the foliage before arching downward and are best trimmed off with an annual cut back of the plant in spring. Plant in part cool sun to light shade and irrigate regularly to occasionally, allowing the soil to dry slightly between watering - surprisingly drought tolerant for a sedge. Cold hardy to about 0 degrees F. It is very striking as an accent plant or ground cover, in rock gardens and in mass plantings in a morning sun or bright shady location. Also useful on the edge of the water garden but dislikes complete submersion. It is on lists as resistant to predation by deer. This sedge, first described in 1914 by the Japanese botanist Takenoshin Nakai, is native to dry forested areas and rocky slopes at mid elevations on the main island of Honshu in Japan. There has been much confusion surrounding the cultivar and numerous names have been applied to it. We originally grew this plant as Carex morrowii 'Old Gold' starting in 1987 and later as Carex morrowii 'Aureo-variegata' . Carex morrowii is a valid name for a sedge that also grows in Japan but following the treatment in Rick Darke's book, "The Color Encyclopedia of Ornamental Grasses" and the New Ornamentals Society listing on Carex, we corrected the name we use for this plant to Carex oshimensis 'Evergold' in our 2004 catalog. We also grow the white-margined cultivar Carex oshimensis Everest Information on this page is based on research conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens where we have observed it. We also will incorporate comments received from others and welcome getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips would aid others in growing Carex oshimensis 'Evergold'.
