Thanks Chuck. So you don't remember which CA rebloomers folks were planning to use.
I've read/heard rumor of similar things by people like Byers, Zurbrigg, Hager, Lauer, Wilkerson, and they all did/are introducing rebloomers. But I can see that the ones with a lot of "CA" genes would lack the cold hardiness to be reliable in zones lower than about 7.
<When reading through old articles from all over the place, for more then the past 30 years, people have been talking about breeding the preferential rebloomers (rebloom in Californai) to hardy norther rebloomers and report that they have or were going to try it.>
? it is <not> a fall cyclic rebloomer here. Unless you consider rebloom in August fall cycle. [I wrote this msg before thinking my way through the whole thing, & now I'm thinking Tea Leaves might be both a reliable preferential rebloomer here <and> a cylce rebloomer. Imm X Viol Classic has produced an unreliable summer blooming seedling here, so .. not sure what that makes Viol Classic.]

Thank you for answering my question.

Byers made lots of rebloomers,  but nothing  that does well here in Zone 4.
I suspected that they might not be cold tolerant enough with all those CA selected genes in there. Most are not disease and late freeze tolerant enough to do as well as most of my own seedlings here, but the combinations are looking good. Tea Leaves has been the strongest Byers iris here that I've tried.
I agree the form from Sky Hooks is not a step forward, but it broadens the genetic pool that works here and from my own seedlings, it (via Tea Leaves) does play well with others (i.e., combined with IMM X Treasured seedling). 


And  the form from Sky Hooks is not a step forward.
