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

The iris season has been weird here.

During a typical spring season, most of the rebloomers begin in the first
week
(of iris season.)  This year, some of the "early birds" did not begin
blooming
until the second week and even later.

Chuck, is it possible that their bloom season is controlled by day length in
the spring as well as in the fall?  Thus they do not respond to an early
season in the same way as the rest?

If not, is there another explanation?
