I live in 6B, .been growing iris since the late 80's and to my knowledge have never had rebloomer's bloom again.I have over 500 TB's.
I agree that it wouldn't be very pretty to have a few blooming amongst the multitude of others that are not.
If you had a bed with mostly rebloomers that consistently rebloomed ,that would be nice.However,even rebloomers aren't consistent in blooming.
When I first started growing iris,I was very interested in ordering rebloomers,but with no success, I quickly lost interest.
