So, I have not given up. So far I have a map from 1906 showing the land undeveloped and then one in 1933 showing the lots on the street. The houses could have been built before the depression. This makes sense. I'm going to see if I can find out when the house was last occupied since it was fire damaged in my memory from the mid 1960's. So, I will assume those Iris are from 1960 and before.
I found a 1953 Dutch Bulb catalog from P. de Jager & Sons Inc. while searching for a De Jaeger Nursery that was indicated on the 1933 map of my town.
https://archive.org/details/CA... It lists four I. reticulata, one being the species, the other three varieties: Cantab, Hercules, and J. S. Dijt.
