I don’t consider Echeveria to be winter hardier BUT when it’s close to freezing, the jades seem to go as a whole plant whereas the echeverias get leaf damage before the stem actually dies/melts (maybe because they’re more protected by the leaves than jades are?). As for sunlight, I consider them equal in that both will take lesser light but look lesser too. Not just getting etiolated but looking “sad” when not in the right sun.

I never thought much of it but I do water all of my rosette-like succulents (not just Echeveria but Aeoniums, etc.) more than jades. Hmm, I never noticed that!

But take all of that with a grain of salt. I’d hardly call myself an Echeveria expert! I just have a lot of them.

Grace, thank you so much! You've told me exactly what I wanted to know. :) It's wonderful when someone answers your questions. Have a lovely day !
