Low-Maintenance Landscaping

Fun Facts

  • 🌱 Red Rooster Sedge maintains its vibrant bronze-red coloration year-round, including through winter, making it one of the most colorful sedges available.
  • 🌱 Unlike many ornamental grasses, sedges (Carex spp.) are non-invasive clumpers that spread slowly by rhizomes and are safer for mixed borders.
  • 🌱 The red coloration intensifies in cooler temperatures and full sun; plants in shade or warm climates may display less dramatic color.
