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?


I don.t think anyone is going to ship the Rz that bloomed in the spring. When new arrivals or even older clumps bloom in the fall but didn't bloom for us in the spring thats exactly what I call them,Fall Bloom. Since LILTING rebloomed for you before than it is a rebloomer in your area.

The *Cycle Rebloomers* complete two distinct cycles of growth, blossoming and increase in one growing season and produce the second cycle of bloom stalks from maturing new increases.



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?



Beardless varieties which rebloom are called *Repeaters*. They produce additional bloom stalks from old growth.



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?



There are even a small number of rebloomers that are *Continuous Rebloomers* or *All Season Rebloomers *that send up bloom stalks throughout the growing season whenever a rhizome or its new growth has sufficiently matured.



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.

LILTING is a very reliable rebloomer here in "rebloomers paradise" A second year clump will have at least three distinct cycles of bloom. Walter Moores GRAPE REPRISE blooms late in the spring but stays in bloom for months so its "continous"

First year clumps may have the best blooms and substance but(for us) rebloom is best the second year. Rebloom declines as the clump becomes crowded with older Rz's.
