Fun Facts
- 🌱 Evergold Sedge is sometimes called 'Japanese Sedge' or 'Oshima Sedge' as it's native to coastal areas of Honshu, Japan, where it grows naturally in moist woodland and grassland environments
- 🌱 Unlike true grasses, sedges (Carex species) are actually flowering plants in the Cyperaceae family; they have triangular stems and lack the hollow, round stems characteristic of true grasses
- 🌱 The golden-yellow variegation can intensify with slight light exposure and cool fall temperatures, making it even more striking in autumn and winter compared to other seasons
