Ok, those are Sempervivum, aka houseleeks or hen and chickens. The babies will continue growing even though the parent plant died, just make sure that the leafy parts are close enough to soil for them to be abler to put out roots. Sempervivums are tough and really like to grow outside in the sun. They are Alpine plants from Europe and they can withstand frost and snow (although not Canada grade snow levels)

Fantastic! Thanks for this great description. Sunlight levels are falling as the seasons turn. Our zone remains relatively warm for most of the winter thanks to the Pacific air, so these plants could probably make it. I have a spare set of grow lights, so I'll set that up.
