Ordinarily an iris would have no trouble regrowing roots and leaves as long as the rhizome was intact and undamaged. However, this is the end of August in MN. It's quite late to be planting TBs here now, esp. those without any roots.

Planted outside, it might or might not survive the winter. Potted and kept indoors in a sunny window over winter, it will survive. It just depends on how badly you want that particular rhizome to survive.

Keep a brick on top of the rhizome all winter.

Pot it up and put it in a sunny window in a cool room. I've got good snow cover in winter and it's still too late to plant. MN has erratic snow cover before the temps dip. Easy enough to buy another but it's kind of fun having house iris. I've had some bloom inside.

Yes, I think it would be fun to keep it in the house over the winter. That hadn't occurred to me. I specialize in cool rooms. :-)

Thanks very much!

Two things about overwintering potted irises indoors:

1) Water minimally. It's pretty easy to overwater potted beardeds indoors, and overwatering can easily lead to rot.

2) Keep an eye out for aphids. Each time I've received irises later than I could plant outdoors, the potted irises have become infested with aphids indoors under lights. It's easy enough to keep them clean if you check them daily and squish any aphids you find, but if you forget, you may be in for a rather unpleasant surprise.

I don't know where you live, but I'm in Tennessee and we can plant irises here well into September. The roots die anyway when you dig them up and the rhizome sends out new roots after it's replanted. I don't baby my irises. Just plant them in a location that gets good drainage because they are susceptible to root rot if they stay too moist, and I leave the top of the rhizome exposed to the weather (since they really are cold weather tolerant). I've lost too many things in pots! Here in Tennessee I'd plant it outside, wish it luck, and then let nature take it's course.

I'm in Wisconsin (Zone 5) and have planted late acquisitions into November.

I didn't WANT to plant that late, but when the farmer down the road roto-tills on a whim and asks do I want the historics that were there since the farm was built, I say a resounding YES!

I didn't lose any that I recall, but I planted them deeper than I normally would and raised them later after they bloomed.

OMG! I was just looking through these posts and saw your post. I thought I was the only person with a dog (and a cat) who liked to eat my plants/gardening tools/whatever else of mine he can get hold of! He took a whole bucket of elephant ear pups that someone had given me this year and not only ate most of the bucket but also scattered the chewed pups all over our 5+ acres. I kept finding them all summer while I was mowing, and when I found one I planted it. Guess what? Most of them came up!! I couldn't believe it. I guess these plants are pretty resilient. (unfortunately, my new peegee hydrangea didn't survive his attack!)

Your not the only one to have critters eat your stuff. Believe me.
I've been swearing a blue streak this past month because most of my carefully crossed and labeled daylily seed pods have been eaten by goats. Plants pretty regularly get stomped by escaped horses and or kids.
Knock on wood the dogs aren't too bad. I've got one old, blind and deaf dog who kind of wanders without noticing much and will snap an occassional leaf. The young one stays at the edge of the garden and sits waiting for me to finish.

I put a little systemic insecticide for houseplants in the soil with the house iris and had no problems. The cats tend to chew on the spider plants anyway.
