Chuck,

The "Summer Rebloomer" are ready to go as soon as the temperatures warm up.
The early blooms were on my 'All Revved Up' (it can bloom from frost to frost)
and 'Lunar Whitewash' followed by 'Matrix.'  Most seedlings showing hope for
summer bloom were in this group also.

Fall cycle rebloomers depend on day length as a trigger.  The later ones (this
spring) are primarily fall rebloomers or so I thought--'Again & Again,'
'Tara's Choice,' Theme Master,' 'Vanishing Act' etc..  In 2006 this group
bloomed before anything else.  (typically do)

'Summer Radiance' has often been my first spring bloom, but this year it was
way behind the earlier ones.  'Star Gate' gave an early stalk, some middle
stalks, and there are two more that don't even show color yet.  SG is
typically later than the rest with spring bloom.

'Over & Over' has been among my most dependable rebloomers, often blooming in
the summer.  It bloomed with the middle group.  Renown was between ARU group
and the Tara's Choice group.  About normal for Renown.

 Linda has also noted this at times.  Most of these should be the summer
ebloomers or as I call them the direct rebloomers.. they respond to a
emperature trigger. So most years are the first to bloom, but with differernt
eather  can sometimes be later. Make note of these as they should be the ones
ou use for "Summer rebloom"  Has to do with going directly from bud set to
lowerstalk.

he iris season has been weird here.
During a typical spring season, most of the rebloomers begin in the first
eek
of iris season.)  This year, some of the "early birds" did not begin
looming
ntil the second week and even later.
Chuck, is it possible that their bloom season is controlled by day length in
he spring as well as in the fall?  Thus they do not respond to an early
eason in the same way as the rest?
If not, is there another explanation?
