    Not cold hardy. Suitable for houseplant
  • Posted by Aeonium2003 on May 3, 2022 9:37 PM concerning plant:
    Should not be confused with Crassula 'Imperialis', or Crassula 'Pagoda village' which are both larger than muscosa. This plant is susceptible to sunburn in hot climates. It produces small dainty flowers from the main stem, and does not form flower heads like many other crassulas do. It can easily be propagated from stem cuttings taken by twisting off sections of the stem. A common plant at garden centers.
