Sempervivum “Red Heart”
I think this is going to turn out to be Sempervivum week here at the blog.
I don’t know why this one is called “Red Heart”. I did some research, and there is no Victorian novel in its background. I don’t know of anyone, fictional or otherwise, named Red Heart. I certainly don’t know any propagators with the nickname Red. Sometimes they name plants after a daughter or niece, and that would seem to be a good thing to check out if I have more time later.
