Hi Carolyn,
I think google personalizes searches now, because I don't have a dutch iris in the center of the fourth row. You can link to the photo by responding here and using the "optional link URL" by copying the address of the picture and entering it into the box.

Is this the iris?

Here is a link that might be useful: Yellow dutch iris

Thanks so much, hose. No, that isn't the one I have. The photos in Google have changed since I asked the question, but I'm trying your suggestion and keeping my fingers crossed.

Radiant Apogee
these are 2 that look like that.

Radient apogee is not a Dutch iris

The photo you linked to is not a Dutch iris, which grow from bulbs. It is a tall bearded iris, which grows from rhizomes. There are perhaps two dozen irises that look similar to that photograph, so it would work best if you could get a good photo of your iris next year so that we could try to help you find a name for it.

Meanwhile, you should make sure your iris is not buried too deeply beneath the soil. Iris rhizomes like to be at the soil surface so that they do not rot from moisture. It will not need too much water this summer, depending on your zone, and will probably rest until next spring when it will bloom again, only with more flowers than this year. At some point you will have to divide the rhizomes, when they get too crowded and start to grow over one another.

You picked a winner with this iris- it's a pretty yellow. Good luck with it!

Take a look at this web site and see if anything looks familiar. You can search the irises by color here- look at all of the yellow and then the orange ones to see if one is like yours.
