Fun Facts
- 🌱 The 'Frosted Curls' cultivar gets its distinctive silvery-white coloration from naturally occurring waxy coatings on the leaf tips called bloom, which also provides some protection from sun damage and moisture loss.
- 🌱 Carex comans is native to New Zealand and is sometimes called 'New Zealand Hair Sedge' due to its hair-like foliage; it has been cultivated ornamentally worldwide for its unique aesthetic qualities.
- 🌱 Unlike true grasses, sedges belong to the Cyperaceae family and have a different internal structure—they're often called 'grass-like' plants; the saying 'sedges have edges' refers to their characteristically three-sided stems.
