The neighbor behind us had an iris garden (lot only 40 ft wide). There were boards to walk on between the rows. He gave a few purple & sort of dirty yellow to my Mom. I used to stand on the bottom rung of a picket fence (built by my father) & chat. there's a pink one i pointed out like he didn't know. It was in the 1940s & it was probably one of the David Hall pinks.
My husband's grandmother had grown irises & had some of the dwarfs. When he saw an ad for the Hagar catalogue hubby said the immortal words, 'oh, they have the little ones' & dwarf irises, especially Green Spot came into our lives. She was a member of AIS & we are life members ourselves.
