I've gradually lost all my C. coum and C. hederifolium; in fact, I lost all but C. graecum. Only C. graecum survives the summer in the greenhouse, bone dry under a bench. The greenhouse is very hot in summer! All the others died in summer if left in the greenhouse or in winter if planted outdoors. C. graecum is starting to bloom in my greenhouse now.
