Here, in my zone 6b garden, I NEVER get fall rebloom on these irises until at
least Sept 15th, but most likely Oct. 1.  


<<I'm still waiting for the main
crop of 'early' fall rebloomers (Violet 
Miracle, Perfume Counter, Matrix,
Harvest of Memories etc) to start 
sending up stalks - plenty of mature fans,
coolest temperatures on 
record off and on this summer, but very dry until the
last week or so. 
I suspect if the predicted cooler temps next week show up
(lowering evap 
& transpiration rate), combined with rain last week, they will
be ready >>
to start stalking soon.

I disagree, Chuck.
Once they reach maturity, they will <not> start 
sending up bloom stalks
unless/until there is adequate available soil 
moisture.

& soil moisture is a
function of temperature, rainfall, texture, 
competition (either from other
parts of the clump or weeds), wind, 
humidity, and preceeding soil moisture.
Plus available soil moisture includes rooting volume/access to moisture.

A
little spritz of rain may keep the grass green, but isn't enough to 
trigger
rebloom in most rebloomers here.

I'm still waiting for the main crop of
'early' fall rebloomers (Violet 
Miracle, Perfume Counter, Matrix, Harvest of
Memories etc) to start 
sending up stalks - plenty of mature fans, coolest
temperatures on 
record off and on this summer, but very dry until the last
week or so. 
I suspect if the predicted cooler temps next week show up
(lowering evap 
& transpiration rate), combined with rain last week, they will
be ready 
to start stalking soon.
