I'm actually not sure if my Mom or grandmother ever bought irises from Schreiner's, but at least some of the more serious irisarians in the area did. I remember the catalogs in the spring and the boxes of rhizomes in the summer, but I don't think they were Mom's or Grandma's. It would have been out of character for them to spend very much money on flowers.
Mom was born in 1941 so you can imagine the influence the Depression/Dust Bowl had on her parents' thinking, and her too to some extent. They did love to grow irises, though.
The Schreiner family has been selling irises a long time, at least since the 1930's (maybe a decade or two before that?). I'm a bit embarrassed to admit that I didn't know there were OTHER commercial iris growers until about a decade ago.
