1)  Echo Location often starts blooming here in August (mid August is the
earliest I've had bloom) and puts up stalks until fall freeze.
2)  Artistic Showoff blooms about six weeks after spring bloom and then again
in the fall.

3-5) were late fall cycle rebloomers, that look almost identical to Rebound
(pod parent) with varying depth of colors.

<< spring and fall bloom dor these seedlings and not just
maiden bloom in fall. Confirmation?>>

 Thanks for the information.
As expected 50% result would be 5.5? out of 11. I'm not sure if 8/11 is
ignificant statistically, but still interesting.
I'm assuming both spring and fall bloom dor these seedlings and not just
aiden bloom in fall. Confirmation?
HoM used to bloom regularly for me, but at new place it has just not
erformed. Just a little bit colder.
Genetically? it would seem both Renowen and HoM are Fall cyclic.? Renowen?
ould seem to be a? FC here.
The FC? condition is? basically a dominant trait, but? not a straight one
ondition.? The genes? come from I aphylla. Basically I. aphylla is a? dormant
lant. It goes dormant, aparently a photoperiod triger. As it goes dormant ,
t lacks? the need? for vernalization to prevent? fall bloom. This lack of
ernalization? seems to be a dominant trait. The dormant gene may be a
ecessive. But in any case when aphylla non-dormant gene is? present without?
ormancy gene functioning, you can get rebloom. If you have more then one
osage of? the non-vernalization gene you can get more then 50%? of rebloomers
n first generation. This may be the situation with HoM.? May also be an
ncompatibility of? photoperiod of dormancy trigger and photoperiod of? bloom
rigger, resulting in blooming being triggered before dormancy triggered. This
ems to be situation with MDB rebloomer Velvet Toy. A first generation aphylla
ybrid. It can fall bloom at same time leaves have been triggered into

 suspect that? a cross of FC X FC doesn't? produces any more rebloomers then
 cross of oncers X FC.? But? FC? may need the? Facilitative vernalization?
ene to fuction as a rebloomer.
More research needed, as always.

   The plants are really crowded now and without getting down on my knees  to
heck, it looks like there are about 11 surviving seedlings from  HoM  X

8 of them have pink flags indicating some kind of rebloom.?

This year, most of the summers didn't bloom until late cycle=frozen  time, so
'm not sure how many of these are cycle and how many might  bloom earlier.
ast year (maiden bloom for the cross), at least one of  them started very
arly (Aug, I think).?

I think RENOWN has "summer" bloomed once here, but rarely reblooms at  all.
oM is a super reliable very early fall cycle bloomer here,  totally different
ehavior from all other cycle rebloomers, which makes  me think its rebloom
enetic "package" is something different from other  cycle rebloomers I've
rown (or tried to grow).?
