Color variations in same cultivar?
I haven't had irises long enough to really form an opinion about this yet so I'm asking the forum. I have two Supreme Sultan irises that were purchased through different sources that have bloomed different. Not REALLY different but different enough to notice at first glance. One has rather yellow standards and mahogany falls and the other has almost mustard tan/orange standards and deep mahogany falls. Could they just be that way from different sources or do I have another case of mistaken identity? I do have Circus World as well that hasn't bloomed yet?
