Unfortunately, my plants are at the edge of my daffodil field and all the identification tags got lost in the last two storms we had. I do know this old yellow is a baby of a hand me down that is ages old. On another site, we were discussing this same topic and it seems that there are some whites and yellows that are newer varieties that are also blooming up this way again.
I am sure with some research you could find some if you were interested. I am sorry I am not much help.
I am wondering why none of my iris get seed pods. I read other people are getting seed pods on their iris and I have none. Can anyone answer that question?
