Hi folks! I planted a nice grouping of some Louisiana Iris last spring (2010). I am happy to say that they have been growing very well in my semi shady bed. But they have not bloomed yet. Is this normal? Do they generally bloom later than other Iris? They are planted beside a "Gerald Darby" Iris which just now finished blooming. Do they perhaps need to grow for a few years before they bloom? Could the shade be delaying the bloom?

I would really appreciate anyone's help with this. Thanks! Big Grin

they do bloom later, not sure about shade conditions.

I have trouble getting them to bloom here. They grow really well, but don't bloom well. Normally irises set their blooms in late summer/ early fall, and I think the bloom buds get killed over the winter.

I don't know what you're lowest temp is Stormy, but that might be the case for you too.

If Gerald Darby is blooming OK, I would think the LAs are getting enough sun.

Thanks Irisarian and Polly! Smiling This year should have been better than last for them getting sun. We had a much cooler spring and the trees were much later leafing out. We did have a true deep freeze this year with a real season long snow cover for the first time in many many years.

The lowest our winter temperature ever goes is 8 to 10 degrees and we might only get 6 to 10 days like that all winter.

These Iris were really short and small last year. Polly, do you think they set buds last fall? Is it too late for them to bloom this year?

They should bloom shortly if they're going to. I would expect they did set buds, even being very small.

They have just finished blooming here, just within the last week. I do have mine in full sun. Oh, and I just thought of something else, I don't think any of mine bloomed the 2nd year. One of the 3 I have may have had one bloom the 2nd year, and I do recall being surprised not to see more blooms because they appeared to be growing well. You may want to wait one more year, then if they don't bloom try a sunnier position. Our winter was worse than it has been for a long time, with some spells of temps from 0 to the teens that lasted a week or more. That didn't seem to phase them, they really put on a great show this year. Are you in zone 6?

Thanks, Neal, yes I am in zone 6. That sounds like good advice.

Stormy, do you know what varieties you have? I've got Black Gamecock, Sinfonietta, and a lovely purple noid that was supposed to be mauve. I believe Sinfonietta is the one that had a single bloom the 2nd year.

Neal, it's six plants all of one orange variety. I'll have to check the name tag when I am home again. I went to look at them today but got distracted by some nearby Ostritch Astilbe that bloomed for the first time ever. Hurray! Lovely bloom form but the darned things were supposed to be pink, not white!! Hilarious!

That's ok, I'm not real up on the variety names, just curious if it was any of the same ones I've got. Seems to me some of the modern hybrids (maybe diploids, increased chromosomes I'm thinking because some are so much beefier in stature) take a while to settle in and start blooming. With the Astilbe, look on the bright side, maybe the white will look prettier with the LAs when they bloom together next year Smiling
