Fun Facts
- 🌱 Evergold Carex is one of the hardiest variegated sedges available, maintaining its golden-yellow coloration even through harsh winters, making it more reliable than many variegated perennials
- 🌱 Unlike true grasses, Carex are sedges (family Cyperaceae), distinguished by their triangular stems—a botanical feature reflected in the saying 'Sedges have edges' to remember their sharper, more defined stems
- 🌱 The plant's Latin name 'Carex oshimensis' honors Oshima Island in Japan, where this species was discovered, and it has been cultivated for ornamental use in Japanese gardens for centuries before becoming popular in Western horticulture
