Hi, Fred, I'm glad you ran this one again. I've been searching through a variety of circa WWII gardening material in search of another reference to orchid iris or Shilka everblooming orchid iris. So far, nothing has come up. There are hits for Shilka (a town and a river in southeastern Russia). Does that Hansen catalog give an illustration? If so, can you scan it and send it out? How exactly is this plant described in the catalog? Jim McKenney
