They may be planted too deep (tubers/rhizomes need to be exposed to the sun) or they may need division. Those are the two most common reasons bearded iris fail to bloom.

Or they are not getting enough sun.

In many cases the rhizomes are apparent on the surface - so likely not that. Should be enough sun also - east and south beds. The south is fully exposed. East is partially since there is a large walnut tree somewhat close to the beds. Still....pretty good exposure there also. Thanks. See what happens this season.

Can you add photos? Sometimes we can see something that hasn’t occurred to the gardener asking the question.

And have you done a soil test? Sometimes plants won’t bloom because of too much or too little of a particular nutrient. For instance, an excess of nitrogen (sometimes from excess from the lawn being fertilized) sometimes causes leaf growth at the expense of flowers. IME most bearded irises like it fairly lean.

Here are some. My apologies for not having weeded in and around all this yet. We've had huge amounts of rain so having trouble keeping up.

As you can see, I have a bit of a problem with wild violets growing in and around the iris. It's infuriating since I can't seem to get rid of them. I hate to go at them too hard since doing so will also dig up or damage the rhizomes. You unfortunately probably can't see the rhizomes (on ground level) as clearly as is usually the case due to the weeds. I'll be working on all the beds in the next few days.

Also, as you'll undoubtedly notice, I have other perennials (mostly chrysanthemums in the one pic) that grow in and around the iris. Will this additional growth prevent flowers? I could easily pull out some of the chrysanthemums. Then in one area there are evening primrose that come up amongst the iris as well (sorry...those things can be a bit invasive I'm finding. I like them but...sheesh).

There are a few other beds where there are patches of iris with nothing else coming up among them - and those don't bloom much either. Any thoughts (other than the presence of weeds...sorry)? You can see a few are blooming and looks today like a few more might be starting.

Here is a better view of the rhizomes after yanking out some of the dreaded wild violets! I swear they grow right on the rhizomes - parasitic little buggers 🤨 Only way to get rid of them (if it even would) I suppose would be to rip everything out and start over. They'd probably show up again anyway. They get into my chrysanthemums too - though doesn't seem to stop them from blooming in the fall.

They look crowded to me. Try dividing them and spreading them out. Or if you have too many, see if someone else would like some.

Way too crowded. In that last picture you can see the criss-crossing rhizomes. This might be your chance to get rid of the violets, as you ARE going to have to dig them all up and replant them with more space, if you want flowers.

OK..thanks. When is the best time to move them around?

Common practice is to move them after they bloom, but since yours aren't blooming, I say do it when you have a free day or two.I'd use a garden fork for both the iris and the violets, if you have one, as it would make it easier.

Maybe it’s just not a variety that blooms well in your conditions. I see a few stalks coming up, so that’s a good sign, but dividing would be a start. You could also try finding a neighbor who grows them well and mention to them you’re having trouble. I bet you’ll walk away with a few new plants lol

dont i see various buds on them????? .. especially those closer to the brick???

are you saying they bud up.. but never open the bloom???

i also think they are too crowded. I would divide the ones without buds now and I’d wait until after the blooms for the others.

You’ve got a lot there. Hope you have a big area :)

In the second photo and in third photo in the clump near the wall, there are bloom stalks. I would want to wait to dig and move until you see if you get blooms or if there are some other issues that effect whether the buds that are formed open into healthy blossoms.
