Product Description
Carex oshimensis ‘Everillo’ (Everillo Japanese Sedge) is a luminous, golden-leaved sedge that brings year-round color and refined texture to shade gardens and containers. Dense, arching blades emerge bright chartreuse in spring and mature to glowing gold, holding their color through the season. Neat, slowly spreading clumps stay compact and tidy, offering bold contrast against darker foliage and excellent definition along paths, borders, and foundations. Inconspicuous spring flowers provide subtle seasonal interest; foliage remains evergreen to semi-evergreen in mild climates.

Care & Growing Information
- Site & Light: Best in part shade to shade; morning sun is acceptable in cool climates. Protect from hot afternoon sun to prevent leaf scorch and maintain vivid color.
- Soil & Water: Thrives in well-drained, humus-rich soils with even moisture. Avoid waterlogged conditions; brief dry spells are tolerated once established but regular moisture sustains color.
- Planting: Set crowns level with soil; space 12–18″ for quick knit and uniform drifts. For containers, use high-quality potting mix with good drainage.
- Maintenance: Low-care. Comb out or shear tired foliage in late winter/early spring; top-dress with leaf mold or compost annually in lean soils. Minimal fertilizer—excess nutrients can diminish compact habit.
- Design Tips: Use as a color beacon in shade, edging paths and beds, or mass for a glowing ground layer. Pairs beautifully with ferns, heucheras, hostas, and dark-leaved shrubs.
