Oh, no guarantees about the rhubarb doing well here. I think it will make it, though. I grew some from seed last year just to try it out and it survived the summer. (Believe it or not, you can grow it from seed.) There still appears to be a little life in two of those pots even though I threw them in the workshop al winter and didn't water them. I pulled them out yesterday and gave them some water in my sunroom. Plus, I bought about 4 more ready to plant.
I hate the delays while waiting for perennials for a few years, but it sure beats always having to grow everything as annuals! When I'm done, I'll have asparagus, rhubarb, a variety of mints, apple, hazelnuts, almond, peach, pear, plumb, and cherries on this lot, plus maybe some other things...depending on space. Oh, grapes, too. Plus the annuals, of course.
Mostly free food once they start producing!
ETA: And blueberries, raspberries, and blackberries.
