Great information Carl, Thanks! I actually live about 65 miles south of Stockton, where Ben had his nursery/gardens, so that information is very encouraging! I lived in Stockton when he was there...but knew nothing about irises, so never got the honor of meeting him.
For those of you who just like to see gorgeous irises be sure you click on Carl's link above for a special treat!!! (That included you Rob! )
