I'm curious about the anatomy of sempervivum plants. There's a hard, white, speckled piece that sits beneath the rosette of many sempervivums. Should I plant this in the ground so it can soak up moisture, or should I keep it above the soil? I'm not sure if this is a root or a true stem, and whether it prefers to stay dry. I'd love to hear about others' experiences with this!

I agree about the picture! Here's an example of what you might be talking about:
. It seems like it was buried, but maybe that's not the best for it.
You might want to leave the white part above ground. That piece usually helps the plant with drainage and can rot if buried too deep in wet soil. Keeping it dry above the surface is often recommended. Just make sure the roots are planted in a good, well-draining mix!
Based on what I've seen, it's best to keep that white piece above ground. It acts more like a stem and can get mushy if it stays too wet. But definitely, a picture helps to clarify things!

Great point! I’ve had some rot issues when I buried them too deep. Now I just leave a bit of the stem exposed, and they seem to thrive.
