Succulents in containers - everywhere: in boxes, in pots, in buckets. They all look like flowers and they thrive on neglect!
Sempervivums often gets confused with Echeverias. Echeverias are fairly hardy succulents, but won’t take the cold temps Sempervivums can endure (well below freezeing in most cases). Echeverias are, for the most part, frost tolerant, but few can survive a deep freeze. On the other hand Sempervivums cannot tolerate the heat of the far south like Echeverias can.
