Someone was asking to see the latest pic of my sedum acre?

Well, as you can see it has finished flowering now.

I do know I can keep it alive in the office window (with a southwest light). But I'm wondering if I ought to thin it and put some of it into the rock garden.

Will it winter there? I live in Toronto, Ontario. I don't know what the zone number is.

It's about an hour and half drive from Niagara Falls, New York. If that helps any.

To make a long story short, we get a frost around the end of October or beginning of November and the ground's hard till mid-March, at least.
