Happy to hear everyone got their Iris. It was so nice to be able to dig, divide, get paided and ship all within just a few days. I wasn't sure there were enough people on this forum to do it, but they seem to do well.
I would not recommend dividing them for at least 2 years. They may not bloom the first year until they settle in and really start looking their best once they clump up after 2-3 years I think.
