Did I send this already?  was having probs with mail server yesterday.

It is cumulative.

Yes, it is the best hope.
It doesn't distinguish between types of rebloom (i.e., what season rebloom starts), and includes all reports of bloom other than spring. The only criterion is that the plant has to have been growing in the reporting garden for both spring and subsequent bloom. To make sure it doesn't report bloom that was "set" in another garden (i.e., fall bloom on a purchased plant that spent spring in another location)

The RIS Checklist, say the 2012 version, it is a cumulative checklist
for the lifespan of all reporting years or is just representing that year?

Is it our best hope for a community dataset whereby to substantiate
category of rebloom "dependability"?

Good question, Chuck.  & not one I'd try to answer, either for
genetics or for garden information.

For my highly variable climates, in order to say for sure that an iris
is a reliable rebloomer here, I would want to grow it for 3 or 4 yrs
after first bloomstalk, without dividing.  I wouldn't know what to
call it if it rebloomed <one> of those years. If I grew it 10 yrs and
it rebloomed twice, I still wouldn't know.

One of the values of the rebloom checklist is that even tho you can't
tell how often it reblooms in one place, if it's reported for a lot of
states/countries USDA zones, they it's probably safe to call it a real
rebloomer.

So a single time reblooming for Shaub, with no obvious rebloom
genetics, may not mean much, but if half a dozen people report
rebloom, even if it's sporadic, maybe it becomes useful information.

As  bloom is a complex relationship of genetics and environment there
can be an odd situation where a plant will bloom twice in a season. The
question is then  how many examples of twice bloom in a season do we
need to classify an iris as a rebloomer. Is a one time report enough to
classify it as a rebloomer? As versus a one off misfire of bloom codes
in response to an unusual growing season?

Thanks Robin. I'll have to trust it's to label since I am not not
familiar with the full field of MTBs. Will post a pic to the photos
listserve in a few days. It has been a good year for me rebloom wise so
we'll see how it does next year.

So we can avoid any false double reports, FYI I am a RIS member so I'll
be reporting it to Region 4 when they ask for submittals. It will be
under Shaub Dunkley, Candler NC. (Z6b)

Another surpriser on the way! Western Hills (per source) (1 yo clump)
has three stalks budding out. RIS '12 shows only VA z6 reporting it so
far. I really expected it to be very sporadic and to perhaps never see
it rebloom for me.

BTW folks, I'm into the historic remontants and carriers. I'm looking to
network with people to help get the endangered ones back on their feet.
You too? Chat me up. I'm a HIPS member as well.
