Arthropodium cirratum, commonly known as the New Zealand Rock Lily, Rengarenga, or Renga Lily, is a robust, clumping evergreen perennial native to New Zealand. It is highly regarded by gardeners for its lush, tropical look and extreme resilience, particularly in dry, shaded spaces. Because of its dense clumping habit, it acts as an excellent weed suppressor and is perfect for mass ground coverings, borders, embankments, or feature containers. Can successfully compete with large tree roots in dry underplanting zones.
