a crushed leaf... for a brief second or two.. might smell like rootbeer but sometimes not ... but all 3 will smell the same.. if the same.. rootbeer or not... ken

Yup, agreed on the ID. You could probably take cuttings a few nodes long & pot them back into mother plant's pot, to make it look even more full & lush.

There are definitely seedlings LOL. It's not going send a stolon 150' across the garden, especially a couple years after it was cut down! In fact I spotted a seedling yesterday and stopped myself from zapping it with glyphosate. I thought, 'heck, that gardenweb thread reminded me of how much I miss that plant'. I might leave it! The foliage does smell weird but only if you crush or rub it. It's not like Zanthoxylum simulans where on a hot day you can literally small the whole plant, and at some distance too. Toona 'Flamingo' is the same, but it seems more "smellable" on still humid nights. Like a strange mix beef and onion soup and burning rubber! 😱 FWIW pretty much all my camellias self seed now. Not to humble brag but I have high quality loamy soil so that probably helps these East Asian plants feel at home.

There are numerous Sempervivums but the webbing points to S arachnoideum.
