Fun Facts
- 🌱 Despite being called 'sedge,' Bowles' Golden is technically not a true grass—sedges belong to the family Cyperaceae, while grasses belong to Poaceae, but they are often used interchangeably in ornamental plantings.
- 🌱 The golden color is most pronounced in partial shade; in full sun, the foliage may fade to a more yellowish-green. This counter-intuitive preference makes it a specialist plant for brightening dark garden areas.
- 🌱 Named after E. A. Bowles, a legendary 20th-century British gardener and plant enthusiast, Bowles' Golden is one of his most enduring and popular introductions to horticulture.
