Fun Facts
- 🌱 Despite the name 'Oehme' often associated with this cultivar, it is botanically classified as Carex oshimensis 'Evergold'—one of the most popular variegated sedges in ornamental horticulture.
- 🌱 Sedges are often confused with grasses but are actually members of the Cyperaceae family; a helpful mnemonic is 'sedges have edges'—their stems are triangular, whereas grass stems are round.
- 🌱 This plant can brighten dim areas better than many other variegated plants, with the golden margins reflecting and dispersing available light, making it invaluable for deep shade gardens where few plants thrive.
