Hi there Rian, don't think its a Buddhas Temple (BT) you have there, but may be wrong. Not got one myself yet but have watched BT's go way over my budget on ebayUK recently!! In my opinion BT's have thinner leaves, more angular 4 sidedness (made that word up I think!) they're a bit like a 4 pointed star, indents in the leaves running up to the tips, and a distinct 4 legged cross when viewed from above. Google for BT 'images' and also for 'stacked crassulas' will give you a link that can't be posted on here.....as a Gweb message has just informed me when I did a preview. Great pics BTW!

LOL, now I'm confusing myself, this is from Altman... https://altmanplants.com/pa_varietycultivar/moonglow/ which looks much closer to yours... Then this... http://forums.gardenweb.com/discussions/3574971/graptoveria-moonglow-blooming?n=2 Then this, see second comment, where kwie suggested it might actually be Graptoveria 'A Grim One'... http://forums.gardenweb.com/discussions/4207131/help-id-graptoveria-moonglow-and-any-advice-for-these-string-of-pearl?n=15 Now compare flowers from Dave (second link above), with the ICN's database for "A grim One'... http://www.crassulaceae.ch/de/artikel?akID=63&aaID=2&aiID=A&aID=153 Now are we totally confused yet? LOL

The issue with this group of Echeveria is no one knows for certain what is what. They are so closely aligned to one another as you will see in the following pictures. the first picture has been ID'ed by John Tragger, HBG as labeled but I can't guarantee all of the others are correctly named. Flowers are on no help as they ALL have the exact same flower. Truth be know, all of these could be the same plant! Kevin, don't go down the Echeveria road.... you will need a new residence in short order as you know after seeing what I have! This was purchased as Echeveria colorata

Today I would love it if it stayed just this colour... it is somewhat shaded by the Japanese Maple but gets full on afternoon sun from around 3:30. NHL, it was an end-of-season purchase a couple of years ago with a full pot of divisions and it just kept growing. It was Barb's mature one that prompted this acquisition. :-). It sounds like so much extra work for you trying to avoid tree roots, NHL. I really feel for you. At the same time, I know the end result will have been worth all the work and frustration.
