Hopefully, you will get an answer from someone more in your zone than me. Here, I would expect bloom this year, assuming the rhizomes are mature & healthy. I think you will get at least some bloom. Here, iris are also greening up some, we've had a week of rather warm weather, a few days in the 60s. Temps are dipping back in to daytime temps of 25-35 degrees, it won't hurt the iris & I would still expect bloom.

Hope yours do the same.

Thanks NGrahm. The reason I guess I'm asking is first of all, because they pretty much the only thing in garden that is happening at all right now, but also so that, if they ought to bloom this year and they don't, if I should be looking for other reasons why (or if I should just toss them all together).

No if they dont bloom this yr, dont toss them. You should get some bloom this spring but if you dont it sometimes it takes a yr or more before they get settled in and bloom. Just be patient, as long as they are getting plenty of sun and not planted too deep.. and a little fertilizer... You should be rewarded

Bearded iris vary in vigor. Some can even take 3 years! Others don't skip a beat.

Thanks for the feedback guys! Sorry it took so long for me to get back here. I will hope for blooms this year I guess and then give them a little more time, I'm not sure if three years is worth the wait of something I have minimal attachment to though...

I'm curious to know how your iris have turned out? It's four months later, and I wonder if they've bloomed yet. I transplanted two different iris last year, one group flowered, and one group has not. I'm more than happy to wait for them no matter how long.

Yes I did space them out. I've been expanding my iris collection for many years now. I have six varieties, some have been here more than 45 years. I may add one or two more colors, if I find good ones.
