Am I on the right page for " plant I D "?
Unknown iris, has rhizome like Louisiana, not a bulb

It seems the only visible foliage is from the yellow iris. The more complete you are with information, the more accurate any guesses will be. Is this a hand me down iris, from the wild, have you seen the seed pods .... any info is always helpful.

Absolutely. More info, and more comprehensive photos (show all parts of the plant), are always helpful. From what can be seen, Iris versicolor?

It is Iris spuria or, possibly, one of the cultivars derived from it.

thanks to all. Will make better photo's this year. These were in Mom's yard when she moved there.

Think I have found the name, spuria Dorothy Foster, web pic; Blue Lassie on Spuria Iris Society page
thank you Kent. Never heard of spuria iris.., another world of plants for me to want more of.
