Here, IMM behaves the way you are describing the "whenever" bloomers. TBs are just finishing bloom late May; IMM can start reblooming as early as June, less than a month after main bloom, sends up occasional stalks through the summer,without shortening days as trigger. BELVI QUEEN is the only other cultivar that has bloomed in July here, I think, but I'm not sure about earliest rebloom date here.
Fall cycle bloom starts with HoM, usually in September, a month before average first frost.
Several cultivars can bloom in late "summer" here (August) if there has been enough cool weather & moisture early - MATRIX, PERFUME COUNTER, VIOLET MIRACLE, GOLDEN IMMORTAL, UNBELIEVABLE LOVE, STAR GATE, FEEDBACK.
Betty is one or maybe two zones colder than me, sees "summer" bloom on several cultivars that are unreliable late cycle rebloomers here - SUGAR BLUES, BRIDGE IN TIME, RETURNING CHAMELEON. All of which seem to grow well here, just don't rebloom reliably & have never summer bloomed for me.
So does that make HoM a summer or a fall cycle? It's first bloom date seems to vary from year to year, but I don't remember ever seeing stalks as early as Aug.
<Whenever rebloomers will rebloom much earlier then a Summer rebloomer. they seem to set flower bud as soon as the plant reches maturity, or so it seems.
For me Forever Blue et ilk, can start rebloom even before TBs finish. .....For me Summer rebloomers start with Queen Dorathy, followed shortly by Immortality. The earliest is about mid August, while Whenever rebloomers can start at end of June, when TBs are just [finishing] their spring bloom. This year, with a cool summer, QD and Imm rebloomed second week of Sept. Three months after whenever rebloomers started.
Thus a sporatic rebloomer that rebloomes in summer, with other Summer rebloomers, is likely to be more similar to Summer rebloomers genetically, and biologically, then to whenever rebloomers. If rebloom is much earlier than summer rebloomers, and not on a delayed fan, then it would be more similar biological and genetically to whenever rebloomers.

not know it's full potential. Other places, other conditions equal other results. Betty Wilkerson> --------------------------------------------------------------------- To sign-off this list, send email to majordomo@hort.net with the message text UNSUBSCRIBE IRIS
