relating to the lemons, I've got a baby lemon seedling in a windowsill in northern Indiana. It's grown about a foot and a half since it was planted about a year ago. I saved the seeds from a lemon from the store, sprouted them in a damp paper towel in a plastic bag, then planted them in a small pot together, originally about five seedlings (I know, a little cramped, but I didn't have much space to begin with) It's mostly grown throughout the winter, sitting in a very drafty window. It's actually in the biggest (and coldest) window in our house, which I'd say averaged 25-30° on very cold days, and 30-40° on good ones this winter. Lately it's been a nice 45-65° so that's nice. The other seedlings sadly fell victim to my cats, who have an addiction to eating anything I plant. I actually planted some catnip in a different pot to distract them from the lemon. Obviously, the lemon hasn't fruited yet, as it's a baby, but it's definitely getting there! it doesn't spend time outside, but definitely has dealt with temperatures below 40° and is still very alive and is growing. My cats still try to eat it sometimes, so hopefully once it gets bigger, that will stop.
