I wouldn't judge type of rebloom right now.
So far this year I have had 4 SDB bolom, that have not seen a winter.
They were grown under lights during winter.
I'm thinking that there is a fourth type of rebloom. This is
Facilitative bloom. May not necesaarily be rebloom.
To back up a few steps, there are two types of bloom triggered by
vernalization. The one is called "Obligate" vernalization. This type of
plant must have vernalization in order to bloom. Obligate = obligatory
The other type is called "Facilitative" This is where vernalization
facilitates bloom. So when plant has under gone vernaliztion it blooms
in spring. When it doesn't get vernaliation, it will bloom later in
growing season, usually after getting a period of warm weather as a
mature plant. Thus vernalization "facilitites" bloom.
Thus these plants can bloom without having gone through vernaliztion. I
suspect that some late Season "rebloomers" in California may be of this
type. As are these seedlings that bloomed without having experienced a
I don't know what genetics of this is, but I'm marking all seedlings
blooming this way so I can cross them to evaluate genetic composition
and interaction. I suspect that by the time winter comes I will have
marked a fair number of them. They are now popping up every few days.
Some of my seedlings doing this have rebloom genes, some don't. But
since over half of this bunch of seedlings have rebloom genes, it may
or not be relevant. I'm suspecting it may not be relevant. I have
gotten this from plants with no rebloom genes and have had it reported
to me by other s from plants with no rebloom genetics.
PS I send some plants to you in mail this am. Expect them early this
week. Mon or Tues. Let me know when they have arrived.
pps: A proffesor at a university has read my articles on rebolom
triggers and will be doing some controlled studies based on them.

Anybody know if HARVEST OF MEMORIES has been reported to "summer" bloom
anywhere? It's 100% cycle rebloomer here.
So far, one of seven seedlings from HoM X RENOWN has a "summer" stalk,
which is pretty close to 1 in 6 ratio.
If I understand and remember what you've been saying, Chuck, that
implies HoM is half "summer" rebloom. RENOWN isn't a consistent
"summer" bloomer, but has summer bloomed at least once here.
Assuming this is really summer bloom and not just a seedling showing
for maiden bloom.
Last winter's batch of seedlings included a few crosses mostly just to
try to learn/understand heredity/expression of summer rebloom under
growing conditions here in the vale. So far, this is the only one to
send up a stalk. IMM X MATRIX cross doesn't have much strength, so may
not learn much from that one.
