My families' backyard neighbor in WI grew iris. They covered his backyard. As a child I used to stand on the bottom rung of our picket fence & talk to him. I didn't know which iris they were, but remember a pink one. It must have been one of David Hall's.
John's grandmother grew 'early irises'. They must have been the early SDBs. We started with Green Spot & Twice Blessed in our small garden.
