Could not resist putting in 2 cents into this discussion.  Certainly some
lines are notoriously producers of irises that are susceptible to rot in the
East. But there are also certain irises that are like alarm signals when I
see them in a pedigree...DENVER MINT, NEW MOON, GIGALO, many of the "browns"
(TOBACCO ROAD), etc.  Even when these irises have been used in out crosses,
the offspring have not faired well here.  Clarence Mahan in VA
