You're right: it is definitely not a Hen and Chicks (Sempervivum sp.) I wouldn't expect it to be hardy in you zone either.

I would like to trade with you. Not sure what type I have either, but can supply pictures as well.

There are at least two kinds of 'Hen and Chicks': Echeveria and Sempervivum, The former does not die after blooming. However, the main rosette will dessicate and die after blooming in the genus Sempervivum. The pups (chicks) will keep on living until they bloom in two-three years. You do not need to 'mess with them', but you can pluck out the dead rosettes from the clumps. Since Echeveria would not survive your winters, I presume you planted Semps. They like to be crowded, and you can grow them as a mat: Practice benign neglect, and they will thrive. Happy Growing!

Hi all, I had posted a response last week that I found it hard to believe that people actually had these guys dying on them. I am posting these pics of my chicks and hens. The first pic is of them where I have planted them around a tree in my front yard. They ALL came fron a 10 inch planter with ONE hen. The next is a pic of 3 I brought Last year that were singles and you can see how they have multipilied many times over and are going in the same bed with the others. I used the cheapest topsoil I could find and I never ever water them on purpose, though they have been in several downpours through the years...Well, look below for the others, sorry. Here is a link that might be useful:
