Re: REB:Rebloom Defined ???

>Quoted from the Reblooming Iris - Home Page:

Unfortunately, none of this mentions anything about the *location* of the 
iris reported as a rebloomer.  One could assume as long as the cultivar 
blooms *somewhere* in the spring and again *somewhere else* later in the 
season, it qualifies as reportable rebloom ... but to which location is 
the rebloom credited?

Again, how does one determine whether rebloom stalks arise from new 
increases on a mature clump unless the clump is dug, cleaned, and 
evaluated for connections?

This is fascinating!  I had no idea the beardless irises rebloomed from 
old growth!  Does this mean *each individual rhizome* can both spring 
bloom and repeat bloom?

This makes more practical sense to me, allowing for any late-blooming 
rhizome in a clump (either the increase from a spring blooming rhizome or 
a separately maturing rhizome in the same clump) to be counted as 
rebloom, assuming some other rhizome in the clump bloomed that spring.  
But I don't understand why this distinction is exclusive to the 
"Continuous Rebloomers" category.  It should, in my opinion, be extended 
to the "Cycle Rebloomers" category as well.
