The archives of the list have a lot of discussion about which iris are weaker
than others and what growing conditions make them not bloom (some of it is
under the 'rot' topic), but we never really had much discussion of what it is
about certain varieties that makes them, for instance, be more vulnerable to
temperature extremes or disease organisms.  

Does it have to do with physical characteristics?  Or is it how the plant
responds to damage?  Maybe that's something that isn't known for iris.

Sounds expensive.  Are you talking about backyard gardeners?  Explain more.
