Chuck, I am new to all this and since I live in California, we do have a long
blooming season. However, I live in the inland valley where it freezes at
night for about two months every year, and the summers can approach 110
degrees. I do not have a "coastal" climate here, nor do most people in
California. Granted, we are not in a "Deep freeze" area like the midwest or
east coast, but there are many plants that can be grown in a true coastal
climate that can't survive here in the inland valley where I live. I suspect
that the TN-KY area may have a climate somewhere in between the two extremes
(mu husband is from western Kentucky)
?
?
I would be interested in knowing
some examples of plants that are "cyclic" rebloomers as opposed to
"facilitative vernalization" rebloomers. Do you have specific cultivars that
you have found good to work with? 
?
I just recently joined the Reblooming
Iris Society. Would that sort of information be listed in the book that they
offer for sale? 
?
Thanks! Geneva

Re: classifying as a Rebloomer

 
 
 
Coastal rebloomer is being used  to
refer to the warm climate  
California rebloomers, that rebloom only in
areas with long growing  
seasons.  I call them  "Facilitative vernalization"
bloomers. Meaning  
that they  bloom better when they have a cold period, but
when they  
don't, they will bloom after about 5 months of growth after  bud
set.   
So if you don't get this long   growing season, they don't
"rebloom".  
These genes are  useless in enabling  fall cyclic rebloom genes,
summer  
 rebloom genes or the Whenever  bloom genes..

Any
examples of   rebloomers that can be attributed to crosses with 
coastal or
occasional rebloomers? 
 
Based on what I know of genetics of rebloomers, I
can't see any 
benefits. And possible  deficits from bring in tender  coastal
genes. 
 
Rare events based on misfiring  of bloom genes  in response to
rare 
growing conditions will not add anything  beneficial to gene pool
information. It will not give any information to aid  breeding. 
 
You need
basic rebloom genes plus good secondary characteristics, which 
include
plant hardiness in  many climates. Good performance in coastal 
areas doesn't
translate into anything useful for harder climates..

Maybe it depends on the goal? 
 
 
If your goal is to collect irises that
will 
have a GOOD chance of reblooming in your yard, then it would be
advisable to 
collect those that rebloom, on a regular basis, in YOUR area.
Learn 
from 
local gardeners. If none exist, you can learn by careful use of
the 
checklist. 
If your goal is to improve or diversify the rebloom class,
through 
breeding, 
perhaps you might want to venture a bit beyond the
default rebloomers. 
??  An 
occasional outcross to coastal rebloomers of
stellar growth habits 
might be of 
benefit.  I work specifically with tall
bearded irises and I'm a bit 
too old 
to begin with inter class crosses
etc. 
 
 
 
 
 
 
&lt;&lt;Once in 20, of no 
value, 
except to be
used as misleading information from the "Spring 
Gardens " of the 
world.
And you can bet that they will use it.&gt;&gt;

For those people 
who have
iris that rebloom  regularly for them, they 
report. And then 
information
is properly recorded.   And expectations 
of   various  rebloom 
in various
zones  can be relied on. Once in 20 
years in zone 4 is not 
information
that can be counted on. 
 
When you check  the "rebloom" iris 
offered by
Spring Garden and ilk, 
you find that they have used  rebloom 
information
from list , sometime 
along the process. When checking out some of 
their
listing I found 
information such as one rebloomer sold in Canada was
recorded as a one 
time event, of rebloom in Australia.  No other rebloom
reported.  This 
iris (along with many other on their list) will never
rebloom 
in 
Canada. Some don't even make it through first year.   Many
people by 
these collections,   both in Canada and USA.  When they don't have
rebloom 
they then can  give up on rebloomers.  Several such  comments 
on
"Iris 
lovers" recently are very likely from this sort of practice. 
 
So
a "once off" 
rebloom from  one iris in one location, when reported 
as a
reblooming iris 
can have unwanted effects.  Even if it is  once 
every
three years , it gives 
useful information.  Once in 20, of no 
value,
except to be used as misleading 
information from the "Spring 
Gardens " of
the world. And you can bet that 
they will use it.

May be a 
matter of neuances, but . . . just because something doesn't
rebloom 
in your 
yard doesn't mean they aren't rebloomers.   My opinion.
'Forever 
Blue' 
doesn't rebloom here, but I don't question that it is a
rebloomer 
. . . 
for 
you and others. 
 
 
 
&lt;&lt;A once off event
of rebloom is exciting, and 
worth 
noting , but 
doesn't make that plant a
rebloomer for  me.  I have over 
the 
years 
have had a good number of
oncers put up an out of season or even 
twice 
a year bloom. these things
can and do happen. &lt;&lt;&lt;&lt; 
 
 
Doesn't make it a 
rebloomer  as
far as I'm concerned.&gt;&gt; 
 
 
'Victoria Falls' did fall bloom for me
in Alvaton, in the 90's.  It grew over 40 inches tall and I quit 
counting at
18 buds.  Don't think it has done this since.  It's my opinion that 
it's
been 
proven to be a plus when breeding rebloomers.  It contributed height,
branching and improved flower form.  Maybe there was another path? 
Maybe
even 
a better path, but nothing else has proven to measure up.

Bloom 
triggers for plants are
complicated, and you can occasionally get 
misfires. A 
number of years ago
in our area some apple trees  bloomed 
in fall. But a once 
off occurrence.
Rebloom yes, but it doesn't make 
these apple trees 
rebloomers. 
Right now
I have  Victoria Falls in bloom, and on a 50" stalk, 
standing up 
straight
and tall. But the only time it has fall bloomed in 
over 
20 years of
growing it. I'm not going to send in a rebloom report 
on it as it 
is a
once 
off event. About 4 years ago I had a fall bloom 
on a clump of Best
Bet. Again 
a  once off event as it also has done 
this once in about 20
years. 
I'm not 
going to list them as rebloomers 
for me in my zone 4
garden. And 
having them 
listed as  zone 4 
rebloomers would be inaccurate
and deceptive. 
Not a 
behaviour you can 
rely on. 
 
On the other hand,
my SDB Juiced Up is 
reblooming 
now on several 
clumps. I first had
rebloom on  Juiced Up about 
2006, after 
initial 
bloom in 1998. It was
interesting, but even if it had a 
rebloom 
parent, 
that still didn't make
it a rebloomer. But in the past  four 
years it 
has rebloomed  three times.
I'll now report it as a rebloomer for my 
climate 
zone. 
 
A once off
event  of rebloom is exciting, and worth noting , 
but 
doesn't make that
plant a rebloomer for  me.  I have over the years 
have had a 
good number
of  oncers put up an out of season or even twice 
a 
year bloom. 
these
things can and do happen. Doesn't make it a 
rebloomer  as 
far as I'm
concerned.
