That repeat stalk of Lavender Fair has just beautiful branching. We
find that often the most branches and buds appear in repeat bloom. I
don't know if it is because they are developing these stalks during
warmer weather or some other cause. There is so much about repeat that
we don't know.
I would agree with Bob that 3 branches is very unusual in siberians.

Hi Chuck -- Ken Walkup has the story right as usual. I've never seen
Caesar Ghost either, but it is supposed to be a white I. sibirica. Jean
Witt would be the person to know where to find it. On the other hand if
you just want a white sibirica to play with genetically, Snow Prince is
another that is readily available and behaves in the same way. Jan and
Marty have used it to produce a range of lovely "neo-sibiricas". The
white x white giving blue offspring is the complementation effect of
sanguinea white and sibirica white because of the different
loss-of-function mutations in the anthocyanin synthesis pathway in the
two species. We do have a copy of the TSI issue with Kevin Vaughn's
article discussing this if you need it.
Regarding bud count, this too is a sanguinea versus sibirica thing.
Sanguinea typically has only two buds (no branch) whereas sibirica can
have many more. Unfortunately, I have never seen as many as the 14 that
Maureen Marks mentions on Banish Misfortune (a sibirica type) but nine
or ten can show up on pure sibiricas under our growing conditions --
four or five in the terminal with five or six more on two branches --
though six or seven are more typical. The hybrids that involve both
sanguinea and sibirica almost always have 3-5 buds with one branch and
4-7 buds with two branches. Under our conditions, it is extremely rare
for me to find three branches on a stalk (i.e. 3 branches plus the
terminal buds as shown in the attached photo of a rebloom stalk on
Lavender Fair) in either seedlings or named varieties. I don't recall
seeing it much elsewhere either -- and it would surely be notable.
However, it can happen. It would be very interesting to find out how
often other people have got three branches on a stem in their Siberian.
Does it happen often and on which cultivars? Bob Hollingworth
