I will speak up about being one that has hundreds of iris and not listing them.
I had hundreds before I ever joined the forum.For a long while I didn't even know about listing my iris until Evelyn I think mentioned it.
At that point ,I didn't want to take the time to do it+I didn't know when I had gotten the iris or what vendor they were from.I have been growing iris for quite a few years.
Then my Month away from 97 year old Mother moved in with me 3 years ago.She has dementia.
I am turning 78 Jan1.
My husband died in 1979 in a car accident.I raised 4 children all very much grown.So it only me taking care of my Mother.
The task of listing with about 600 different iris is too much .
I also really don't want to trade either.If I were 10 years younger,trading might interest me, but not at this point in my life.
