CULT: Bellweathers

  Taking a cue from Anner's suggestion, I calculated the median date of
  (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, 

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.
