There really are no orange irises that rebloom here.  Amanda Erin bloomed for
me the first fall that I grew it, but now I'm having trouble keeping it alive
and can't even get spring bloom.  As a color class, they tend to be weak, but
some of the older warm weather rebloomers do survive here--Gratuity & Fringe
Benefits.  Grew and loved Orange Empire & it appears to be a good carrier.
Working with recessives in this climate is a challenge.  The late spring bloom
of the entire class also hinders work. Flaming Victory has been tender here,
but I'm trying it again.

Vigor has always been high on my list when choosing seedlings.  There is a
difference between early growth and vigor.  It's easy to confuse the two.
There are rebloomers that do not bloom with the earliest wave of spring bloom.

With the weather changes, the trick is to get ANY rebloom early enough to beat
the first fall freeze.  A good fall season has become as scarce as hen's
teeth!  My goal is to get rebloom early enough to enjoy it here in my zone 6
garden.  Most of the fall cycle rebloomers just don't bloom early enough here.

I have one fall cycle rebloomer that is giving good steady (3 years) rebloom
starting in mid-Sept.  It did skip spring bloom last year.  It grows well and
has height & decent branching.  I'd like it to have more ruffles etc.., but I
may introduce it eventually.

<<My money is on getting good fall cylic rebloomers for your areas will be a
much fster process then getting  good summer rebloomers.>>

Since maturity of the rhizomes seems to be the key to rebloom, the real trick
may be to grow the rhizomes in the spring without maturing them enough to
bloom.  Fertilizing right after spring bloom has always been advised.  Maybe
this is the key;however, high heat begins before the end of spring bloom these
days so it may be a challenge to do so without inducing rot.

 By selecting  the most vigourous growers and ones with lowest mature leaf
ount, you move  bloom time forward.
The weather conditions that set flower buds is the same for summer rebloom
and
all cyclic.
The weather conditions that inhibit  rebloom is the same for both.
So if a plant matures fast enought to get bud set before  too warm weather
ets in, you will get  early fall cylcic rebloom.  Same with summer
ebloomers.
So which ever line of  rebloom triggers you are looking for, vigour and  low
ature leaf maturity  will get you there.
But with Summer rebloomers you have more of a problem recovering genes in out
rosses.
My money is on getting good fall cylic rebloomers for your areas will be a
uch fster process then getting  good summer rebloomers.
If HOM can do it , others FC  can as well.

eah, I know.  But I don't want fall cyclic - nearly all of them are so late
hey freeze out so are worthless here as rebloomers.  Except HoM.

 Then pick an orange that grows well for you. If yopu have a number to pick
rom, choose one wioth lowest mature leaf count at bloom time.
There's the problem - I only have two oranges that grow for me (one grows
ell, the other has hung on for years, so I guess it grows 'well' too,
ompared to everything else). Sibs from GOLDEN APPLE X CRYSTAL GLITTERS, pale
range.
Haven't ever been able to keep a storebought orange alive.  Did manage to get
ollen from AUTUMN RIESLING before it croaked.
2009 was another bad pod year, so had to fall back on the survivors, wound up
ith pods on IMM, HoM, MISSOURI MIST using my orange seedling pollen.
ubstance is likely to be really soft on all of these. :-(, but at least they
re super robust here.  Two surviving older seedlings from the same cross with
MM have been winter bloomers ;-)  November cycle. In years when hard freeze
as held off till then.
It would save me a lot of time if I can find a modernish "summer" reblooming
range, no matter how puny, that I can coddle in a pot long enough to get some
ollen to put on the best from the above.  AUTUMN ORANGELITE is too big a leap
ackward!  Tho I probably will experiment with it if I can't come up with
nything else.
Been getting some deep saturated yellows from HoM X various pinks, occasional
 beard.   But not breeding for rebloom till now.  Hence my wish for a
eblooming orange to mix some of the above with.
> Some of your seedlings will be FC. Then? cross? best back to the original
range, or to best sibling. Crossing back to orange will get? you ther sooner.
