Re: CULT: rot-prone irises

Laurie, if you will post your list of 'new' irises, maybe we can help.

I hate to think of trying to compile a list of all the irises that have
ever rotted here from freeze damage, drought, deluge, and other
miscellaneous stresses here (livestock trampling, deer snacking, hail
storms...).  Plus I've learned from this list that some cultivars that
never rot in other regions, nearly always rot in my region, and (to a
lesser extent) vice versa.  Jeff Walters, Utah,  and I have swapped some
good growing healthy cultivars with one another - almost exact opposites
in what does well and what doesn't for many cultivars we've exchanged.

Sure do wish there were a region by region 'rot' sensitivity (which I am
convinced translates to a stress sensitivity) index for cultivars,
something like the rebloom report, where each cultivar gets a score from
anybody who tries to grow it of 1, 2, or 3 depending on whether it dies,
stumbles along, or thrives.  With the same kind of caveats the
reblooming recorders have - it has to have lived in its new home for at
least a full bloom cycle (year).

Maybe we can start a 'Rot Resistance' affiliate of AIS <g>

Laurie asked:
<Would you all be so kind as to send me lists, either
                 publicly or privately, of those iris cvs that have
experienced rot
                 problems in your gardens?>
