I'm in Nova Scotia and have a very similar plant... pups like crazy and can't be killed. It came unlabeled, though...

Impossible to identify. The look considerably different in different growing conditions. Also, new cultivars come and go and names are sometimes invented by merchants. One thing you can do is look through online nursery sites like simplysucculents.com and see if you find something similar. You may well find two or three that look just like it and you'll never know which one it is, and at that point you'll realize it doesn't even matter.

Could be Sempervivum Tectorum? They are really hard to identify, as tcstoehr says. Do you have an image of yours flowering?

Here are some Sempervivums, also from Toronto, which look quite similar. These ones get even darker tips like yours, depending on the amount of sun. They pup and grow quite quickly outside for my friend's parents. Unfortunately, she didn't have a photo of the flowers. She said they grew on a very strange hairy stalk.

They grew a large quantity of them - here is the progress of that (to show different plant stages):

I've had a baby one since last September and it has maybe doubled in size, if that. It's been growing very pitifully inside (as well for my friend):

It is a variaty of S. calcareum. Close to the old hybrid S. Birchmeier.

Harry - is that for both of us? Thanks for the help!

Hi,

For the first one.

Your 'nursery' look very healthy, but I cannot give a name.

There is calcareum in it, but thats al I can say.

If you let them color up with more sun and maybe less water, maybe then.

Harry

Thanks everyone so much for your input!
