Taking a cue from Anner's suggestion, I calculated the median date of
bloom
(in the statistical sense) of each of the classes of iris I grow for the
past three years. The "median date of bloom" for a given year is the date
on which one-half of all the cultivars to bloom in each class have opened
their first bloom. The results are as follows:
MDB SDB IB AB MTB TB/BB SIB SPU
1996: 4/29 5/11 5/15 5/22 5/27 6/4 6/15 6/19
1997: 5/6 5/15 5/18 5/20 5/17 5/31 6/5 6/21
1998: 4/28 5/16 5/20 5/27 5/22 6/2 6/15 7/4
Among IB's DARK WATERS and FIREBUG and among TB's HONKY TONK BLUES and
OUTRAGEOUS FORTUNE seemed to be good indicators ("bellweathers") of these
dates for their class. I am probably not gtowing enough cultivars in the
other classes to be able to pick out the bellweathers.

I'm excited about this project! I think it could be very valuable
information to collect! Furthermore.... since Jeff is way ahead of us in
record keeping, I would nominate him as Project Coordinator! How about it,
Jeff??
Seems to me that the first thing we need to do is to decide what we're
tracking. I would suggest that what we need to track is a reliable harbinger
of a season - and we need to select cultivars that have a reasonable chance
of surviving in every climate. HONKY TONK BLUES is not reliable for me....
So I guess we have to take in information this year, and then decide which
irises to use - and purchase them (if we are not already growing them).
I think that this is JUST the kind of information collection that makes the
internet such a valuable tool... and I'm excited.
