Fun Facts

🌱 Carex comans is native to New Zealand and is sometimes called 'Bronze Hair Sedge' due to its fine, hair-like foliage that can measure just 1-2mm in width.
🌱 'Milk Chocolate' specifically was selected as a cultivar for its intensely warm chocolate-brown color, which deepens considerably during cooler months, providing four-season color interest.
🌱 Unlike true grasses, sedges (Carex species) have triangular stems rather than round ones, leading to the old botanical rhyme: 'Sedges have edges' (triangular), while 'grasses are hollow and round.'
