Hi, y'all! y'all were so helpful with an iris ID for me last week; I have two more for you! These two came from an old homestead north of here.

These two will be much harder to identify. No unique identifying marks/colors/beards like your last iris had. Could be old historic cultivars or just seedlings.

Oh, that's disappointing. Oh, well! They're still very pretty!

with Laurie, yellow and Purple colored irises are so common that they'd be hard to identify. The yellow looks like it could be a historic due to the darker veins on the falls near the beard. The purple one could be an MTB.

purple is wrong form for most MTBs.

Ok, I'm showing my ignorance here. What's an MTB?

MTB stands for miniature tall bearded iris. It is one of the median classifications with a height limit of 26 inches and a 3 X 3
inch flower size. The flower is way too large on the p urple iris.

Thanks, Lucy! Yes, mine are way too big to be classified as minis. The flower stalks are approximately 4.5' tall!

historic of some sort?

That's what I think. And many others think so, too.
