Fun Facts

  • 🌱 Coprosma is a genus native to New Zealand and other Pacific islands; the name comes from Greek meaning 'bad smell' because some species have unpleasantly scented foliage when crushed.
  • 🌱 The 'Green Gold' cultivar's striking variegation intensifies with more sunlight exposure—plants grown in full sun display more vibrant golden coloring than those in partial shade.
  • 🌱 In warmer regions, Coprosma robusta can reach 8+ feet tall and is often used as a clipped hedge in New Zealand gardens, sometimes even for creating topiaries.
