    Sempervivum 'Red Rum' has excellent coloring.
  • Posted by valleylynn (Oregon City, OR - Zone 8b) on Sep 1, 2012 7:29 PM concerning plant:
    This semp has been in my collection for a full year now. It is one of the largest in the collection at about 10" across the largest rosette.
    It has not had any problems with rot during winter/spring rainy season, or dehydration in our over 3 months of drought.
