Hi Betsy!
Your bright yellow Iris *may* be Ola Kala. I'm including a photo of mine so that you can compare. If you think this is a possibility, to be sure of a positive identification, you'll need to buy a rhizome of Ola Kala from someone reliable -- and then plant it next to yours to see if they look exactly the same, side by side.
A side-by-side comparison is the only way to be sure of what you have.
