I'm finding ta lot of different things on the internet rabbit-hole about irises in the bog. Planning out a new bog filter for my recently completed pond and I'd like to have a variety of irises in the gravel. Looking for types or iris that will grow in the bog and survive winter in Michigan. I've seen some info that Louisiana and Siberian irises are suitable for the bog but then some that says only 'true' water irises are. Would appreciate any clarity/suggestions on appropriate plants. Thank you

And the siberian and louisiana are in the gravel, below the water line?

I have some in the water no soil, some in the bog, pea gravel, some in pots, kitty litter, all do great. We do freeze.

I have some one and two year old LA irises that don’t want to bloom. They appear very healthy otherwise. Any suggestions?

I believe I have deep purple almost like the color of a royal Cape they are in the water but only like 3 inches and they don't seem to like to bloom either. It's been so long I can't remember if they were bearded or not

It can take abit for them to really get going,Ime. The irises I have in my pond and bog didnt do much for the first year or so, then they take off and bloom like crazy.

One is in full sun with its crown at water level, the other in part shade in a marshy area. Each has about two square ft.

Hopefully they're just building up strength and reserves to really put on a show down the line. As Jhn said, they can take a couple years to establish before they decide to flower.

Blue Flag Iris is my fav. Native in the U.S. and does really well in the bog. Slowly spreads but hasn't been to aggressive or anything for me.

Irises don't seem to want to bloom if they're planted too deep in the water either. My Siberian bloomed great when the crown was above water... not so much when they were deeper. The plants still grew - just didn't do much blooming.

Then again my yellow flag is blooming like crazy this year and it's in the exact same place it's been for five or six years and usually gets 3 or 4 blooms... so who knows!
