Easily grown in medium to wet soils in part shade. Foliage color is richer in part shade than in sun. Plants tend to languish in full shade. Plants thrive in moist soils, but also perform well in average garden soils, with better tolerance for periods of dryness than most sedges have. Plants generally dislike hot and humid summer climates. Plants are evergreen throughout most of their growing range. Where not evergreen, foliage should be cut to the ground and removed in late winter. Plants spread slowly by short rhizomes. Propagate by rhizome division.

Noteworthy Characteristics

Carex oshimensis, commonly known as Oshima kan suge, is a fine-textured sedge that typically grows in a low, grass-like mounded clump to 10-16” tall and as wide. It is native to dry woods and rocky slopes throughout Honshu Island, Japan. This sedge features narrow leaves (typically to 16” long by 5/16” wide). Insignificant brownish flower spikes appear on triangular stems in spring. This sedge is evergreen in the deep South, maintaining good foliage in both summer and winter. It is not totally evergreen in the St. Louis area, although some foliage color will persist through mild winters. Plants are similar in appearance to Carex morrowii.

Genus name from Latin means cutter in reference to the sharp leaves and stem edges (rushes are round but sedges have edges) found on most species' plants.

'Everoro' is a naturally occurring mutation of Carex oshimensis `Evergold` that was discovered by Pat Fitzgerald in 2007 at his nursery in Stoneyford, Republic of Ireland. It is a member of the Evercolor® Series, sedges with variegated foliage that were developed by the FitzGerald Nurseries and are in the Southern Living® Plant Collection. 'Everoro' is a compact, clump-forming, evergreen sedge with golden yellow leaf centers and wide, dark green margins. It grows 1 to 1 1/2 ft. tall and wide.
