This is a hardy Sempervivum perennial which can be left outside in zone 6 area. It's been through snowstorm and hot & humid weather. It is extremely hardy and look what it rewards me this year. The flowers are not super pretty but I was surprised to it bloom. The other two are succulents I added this year and they are also easy to maintain. Just make sure they're in full sun, and just water a little bit when it's dry.
