Re: Fwd: Re: HYB: older seedlings, rebloom


We need some guide lines for collecting empirical data.? 

What about variables?? Unlike a lab, it would be impossible to standardize the various gardens.? As the crow flies, I'm five miles or so from my Alvaton garden. (1980's & early 1990's) and I've several irises that grew there but don't here and the reverse.? 

Currently, I'm in farm country.? My garden is a?former pasture, a wide open field with a southern slope.??Tilted just slightly to the west.? No trees or shade of any type.? I'm on a creek bank, in fact, I'm in a loop of the creek.? I get a lot of fog and dew.?? We know I have a security light.? 

I can record fertilizer etc.. but only in general terms as hand application is variable.? Can record timing sequence on soaker hoses etc..

I keep a garden journal with the high/low temps given by our local (20 miles) weather station, and a rough estimate of rainfall.? The temps are a degree or two off at times given the difference is local.??

 Clearly, the types of rebloomers used would factor into the situation, with good hybridizing records.?

Is it doable?? Would people be interested in contributing??

next step is to get some imperical evidence, and put theories to test.>>

Renown  reblooms here, but I havn't tried Autumn Twilight, so not sure
what type of rebloomer it is.

In any case, the vigorous seedlings will likely be the best prospects
for rebloom, or for breeding for rebloom.

I havn't seen Winterberry Catalogue for 2008, but I do agree with Don
on some things and not on others. So far we have a lot of theories,
next step is to get some imperical evidence, and put theories to test.

Speaking of rapid growth, I have a small batch of seedlings in a pot
from last year from RENOWN X AUTUMN TWILIGHT that are putting on a huge
growth spurt.  Compared to everything else, they are about two weeks
ahead in growth.  So far, no conspicuous damage to that lush (not at
glaucous or bluish like pallida) foliage in spite of the up and down

I expect these babies to produce really retro blooms, but was hoping
some more summer bloomers to keep me entertained while waiting for
better things.  At least I <thought> these would be summer bloomers
before the recent discussion about rebloom genes. ;-)  Don Spoon has
some discussion in their catalog that came yesterday about genetics of

Chuck, do you and Don have more or less the same understanding of the
genetics of rebloom?

Any guesses about what to expect re: rebloom frequency from this cross?

This will be the first year to see a bunch of seedlings from the little
SDB BEING BUSY lookalike (that grows out of class in Oregon -
what it takes for an SDB to bloom normally here!).  Fans on many of
these TB X SDB kids are really wide, even wider than many of the TB X

Is that an indication that these will be more like TBs (or BBs) than
IB's?  How frequently do the genes sort out as TBs vs shorter things in
this type of cross?

Hybrid daffs are at peak here now - weather has been mostly cool, plus
regular rain.  The blooms are huge and happy.  When is the usual
freeze due?  Will it peak in Texas this year or farther east?
