That first one reminds me of one of the "recurring" series of blue/violet rebloomers ( I think they were Hager irises?) anyway, check around for some pics, maybe the AIS wiki, or the data base here, and look for Recurring Dreams (or Delight). I don't grow any of them (yet, anyway !), so I have no pictures, but they would be mostly late 80's, early 90's intros, so the time frame would be right ....Arlyn
