Francine, I already ordered (and received) the ones I'm bringing to people at the swap. If you find out you're coming, I can spare one or two trays, but there aren't any extra humidity domes. Although you'll be missed, I think you should see if you can get another ticket and go to the concert with your friend!
Josie helped me divide some water iris the other day. She was dripping with black muck to her eyeballs!
I think I have both japanese irises and louisiana irises in my water garden pots... are the japanese the ones with the thin, almost grass-like leaves?
