Where Does It Call Home?

This little beauty is endemic to California, where it naturally occurs in the Sierra Nevada foothills and Central Valley regions. As a native species, it’s perfectly adapted to California’s unique climate and plays an important role in local ecosystems.

  • Ground cover superstar: Creates lovely carpets of color in rock gardens and naturalized areas
  • Native ecosystem support: Helps support local wildlife and maintains regional biodiversity
