Cinta, I'm as confused about that as anybody! No idea which, if any, hardy Sedums need a cold period. I'd never heard of Sedums as house plants until 'discovering' that I actually do like cacti/succulent plants so recently. There's a whole different crowd of those. I get very confused trying to investigate the hardiness of some of them (if I can even figure out what they are.)
In OH, one can't throw a rock w/o hitting an 'Autumn Joy' plant, prob the same way in PA. But haven't seen any of the *MANY* hardy Sedums I'd collected in OH, to play with here. If you give it a try, letting the cuttings callous overnight, up to a few days, would probably be a good idea & I look forward to updates if you do.
I have tons of unorthodox ideas for plants... a lot of them actually work! LOL! Either way, trying is a blast to me. Glad to infect anyone with experimentitis! ;)
