2007 was my best year for rebloom here in north central
Texas zone 7. Here is a list of iris that have rebloomed for me.
An Unknown that I have tentatively identified as either Pearls of
Autumn or Returning Chameleon
Dawn Of Change
Earl of Essex
Dark Vader- this one bloomed in April, May and June but not in the fall
Witch Of Endor
Immortality has bloomed in the fall for me but never in the spring.
