Hi Catherine.
I started out with the named hybrids and came late to loving the species type sempervivum. There is a beautiful simplicity to them.
I have been learning that about many bulb type plants in the last year, from you.
I think you are learning very quickly Catherine.
I have been so busy adding to the database here that I have neglected by learning of species bulbs. Soon some of mine will start blooming and I will be on the trail of learning again.
I got this wonderful species (Sempervivum tectorum costigliole, piemonte mts, italy) from Mesa Garden in New Mexico. They have the most amazing plants when looking for species type succulents. I got this semp from them last year. It is quickly turning into one of my favorite sempervivum.
