I cheat. It reblooms in cold greenhouse. but just slightly after killing
frosts ouside.
?
And in my climate I do get the cooler nights that enable rebloom? earlier then
a lot of more southern climates.

Interesting, Chuck -- I've grown Lenora Pearl for many years and never
suspected that it was a rebloomer, since it never has here. Yet it reblooms
for you hundreds of miles to the north! -- Griff?

Depends.?
??
In a cross of Lenora Pearl X October Splendor, both rebloomers here, and
seem?
to be FC, there were about 25 seedlings. Absolutely no rebloom. My take on?
this is that with Lenora Pearl as pod parent the plants inherited LP's plant?
habit. October Splendor has a high mature leaf count. So the combination of?
secondary genes just didn't work. I'm willing to bet that either of them?
crosed to my Buckskin Babe, (a tttt plant) and a oncer, would produce good?
rebloom in my climate. A better genetic combination for secondary factors.
And?
BB would probably make a better pod parent then a pollen paent. I'm marking
it?
down as a planned cross?
??
I haven't grown Pink Quartz, so don't know how hardy it is, how fast it
grows,?
or what it's mature leaf count is. Isn't HOM's mature leaf count fairly
high??
??
I'm seeing FC as being two dominant genes working together. 1) Non?
vernalization of flower 2) not light triggered dormancy plus secondary
factors?
of flowering timing. So if FC has one each of these dominant genes, 1/4 of?
seedlings would have one copy of each So out of 14, 3-4 would be expected to?
have FC genes.?
??
Having the potential, and being able to use it are separate issues.?

Another observation - 14 &lt;very&gt; strong surviving seedlings from
HARVEST?
OF MEMORIES X PINK QUARTZ. 100% survival of seedlings first lined out in
2008?
(or maybe 2007?)??
??
None have bloomed other than spring. If cycle rebloom is dominant, wouldn't?
you expect at least one of these to rebloom???
??
Come to think of it, other than the cross with RENOWN, I don't think I've
seen?
&lt;any&gt; reblooming seedlings from HoM here in spite of a lot of crosses.?
Will have to go back and check my notes. I can think of three different?
seedlings from HoM that have had fall maiden bloom, never bloomed other than?
spring since.??
??
Or does that imply HoM is actually a summer or something other than cycle???
