Did you know

  • The genus is named after Meriwether Lewis of the Lewis and Clark expedition, who collected the first specimens.
  • It grows naturally in rocky crevices in the Siskiyou Mountains of Oregon and California.
  • The succulent rosette of leaves stores water, allowing it to survive on sheer cliff faces.
  • Crown rot from excess moisture kills more plants than cold, so excellent drainage is essential.
  • Hybridizers have expanded its color range from the wild pink to include vivid oranges, peaches, and bicolors.
