hardy cultivars

Clarence Mahan:

 Thanks for the info on the concurrence of types that seem to survive in both
climates, but do you have Afternoon Delight or Fancy Dress or other iris with
several colors that do as well?  Is it because as you get into the fancy
bicolors, plicatas, etc. that the hybridizer has gotten farther away from the
original species and therefore they are not as tough?  Just a thought.

i agree with the horror - i see trends to rot in certain colors too - those
beautiful lavenders,  some reds (others are some of the toughest), bronze (I
haven't tried many), amoenas (same as for reds), and those pale yellow with
lighter falls with yellow rims.  i have had success with oranges (should we
swap trial lists?) and some pinks, although pinks tend to lie around and mope
a lot.  as a group, blends seem to have least rot (outcrossing vigor?).  

and it isn't the breeder's fault they live in a better climate.  my apologies
if i insulted somebody.  it s too much trouble to say "in my experience,
varieties developed by so and so are more likely to rot here than varieties
developed by so and so, so to save money i don't buy them unless i find
someone else who has grown them near here successfully".  so i say, so and
so's varieties are prone to rot.  can we have a cyber convention for
this?RILG -  rot in lindas garden, or AHRILG - always have rilg.i can't
remember acronyms..
to - i think michael adams? or  Janis Whitcomb, Auburn, WA ?- thanks for the
shared survivors! i had about given up on hearing suggested varieities.
 maybe this isn't the time of year.  i agree about old Dyke's medalists - a
good cross check is looking at date of introduction versus ranking in the
yearly AIS popularity poll - the old ones that still rank in the top 100
aren't as likely to rot.  One other interesting thing i learned from talking
to growers is that other people have a hard time with reds!  so whatever it
is we have that is bad for other colors may be good for reds.  
my iris rot and spot but they also have mysterious wasting disease - i never
have worried about what it is - they just sit there, gradually shriveling up,
usually not making many new roots.  Usually gone by the following year, but
some linger longer. some with this disorder seem to do a little better
depending on soil microsite, but never do well

to name names again, i am trying shriner's seedling trial this year - the
amoena has rotted already.
