Re: Re: HYB: REB: mixing cold climate & CA; pH

Yes Mike
That's the ones that will occas rebloom on acid soils such as Momentous Occasion. However apart from the year I imported them many of the others have never rebloomed, such as Autumn Thunder and Deja Blue.

Feed Back is a great multiple bloomer here....maybe were getting somewhere. Don't have Star Gate. Some of Betty's stuff has rebloomed for us in the summer, in fact some of her kids rebloomed for us that never rebloomed for her (correct me if I am wrong Betty). Some of our stuff ends up doing well and reblooming in cold climates like Raspberry Frost, Double Shot and Golden Immortal. Am starting to be able to see indicators here to which ones will rebloom in colder climates. More than anything, if a flower is a multiple rebloomer here *and* has heavy, consistent rebloom, it should rebloom just about everywhere. By heavy, I mean spring-like. Autumn Tryst is what I would call a heavy multiple rebloomer. Does it do well for you Linda? Colleen has a lot of our rebloomers and some of them do well for her, in fact, some rebloom for her that really never rebloomed here.......

Thanks everybody for all the feedback. After I posted my question, I realized I hadn't thought through what I really wanted to know, but you guys answered me anyway.
One of my long-term goals (will I live long enough??) is to have "everbloomers" with the health and vigor of IMMORTALITY here with much better stalks and blooms, with moderate garden care.
Mike Sutton posts photos of his seedlings that bloom in very hot weather, so I know the heat shouldn't be a limiting factor for rebloom, but it is here for the cultivars/seedlings that are strong survivors. Because of the extremes of growing conditions here in 'the vale', I've not had much luck making crosses with Sutton everbloomers (i.e., getting them to do well enough to provide pollen).
And the everbloomers that thrive here (i.e., "cold climate" rebloomers) don't rebloom for them.
So, I was wondering if anybody has had luck combining lines that everbloom at higher pH (i.e., CA everbloomers) with the "cold climate" rebloomers that rebloom at lower pH?
Mike, from your post, it sounds like either (1) the suite of rebloom genes from IMM and your lines didn't combine to produce rebloom, or (2) your seedlings inherited IMM's cold climate rebloom traits.
I don't trust my memory, but I <think> GOLDEN IMMORTAL has summer bloomed here. FEED BACK has definitely summer bloomed here. And seems like I remember STAR GATE summer blooming here. 

Is anything in the pedigree of FEED BACK a CA everbloomer?

Do FEED BACK or STAR GATE "everbloom" bloom in CA?
Betty, do you have a CA 'trial garden' to see if any of your kids everbloom in CA?
Or have you tried raising the pH to see if that will trigger summer bloom here? I think you said no to that one.
Have the folks in Oz who were doing the pH comparisons to see how it affected rebloom identified any 'everbloomers' that rebloom independent of pH?
