I now have 3 ~ 3 ' tall ** and > 40 seedlings of 7 varieties ~ 3 - 6 inches tall. Don't ask, I have no freaking idea.
My oldest from 2014 over wintered in my living room near an East window.
My new ones purchased in Fall 2015 were a rooted and unrooting cutting from Dr. Dawg. I kept them in my basement grow area and they are doing fine. All are out for past week or so on my screen porch getting screened light to harden them off.
