History

Illustrated historical scene for Evergold Sedge

Carex oshimensis, commonly called Oshima sedge, is a low tufted evergreen sedge in the family Cyperaceae endemic to the Izu Islands (particularly Oshima Island) and parts of southern Honshu, Japan. Japanese botanist Takenoshin Nakai formally described the species in 1915. Plants form compact fountain-like 20-40 cm wide mounds of glossy narrow strap-shaped dark green leaves that cascade gracefully.

Small brown flower spikes appear in late spring but are not ornamentally significant. The species has become globally important in horticulture through several major variegated cultivars: 'Evergold' (yellow central stripe with narrow green edges), 'Everest' (white-edged green), 'Everillo' (chartreuse-gold all over), and 'Eversheen' (bright yellow-green). Collectively these EverColor series sedges from Pat FitzGerald in Ireland (2010 onward) have become among the best-selling ornamental sedges worldwide, valued for evergreen habit, tolerance of part-shade, and bright foliage effect in winter gardens.

Hardy throughout much of the temperate zone. The 'Evergold' cultivar revolutionized American shade gardening in the 1990s by offering bright variegated evergreen color—a rare combination. The newer 'EverColor' series from Japanese breeders has made these sedges among the most planted in modern American landscapes.
