We live in B.C. as well, down near Vancouver. I know a bit about trees, not much at all about succulents.
We've had this succulent that we picked up at Granville Island Market some time ago. It's never been robust and I'm pretty sure it is not long for this world.
My questions for you:
>> What is it?
>> Is there a way to save the live growth at the top of the plant? Can it be 'propagated'? Any pointers?
>> Is there anything you can tell us about how it got this way? was it over/under watered? Something else?
