What an interesting mystery.
There are all kinds of possibilities.
Your seedling might just be a large diploid. We have some diploids with very
large stalks and flowers, though not five feet tall. That combination sounds
terrific.
Do you have tetraploids in other parts of your garden? Bees can travel quite
a distance with pollen. It does not seem likely that Ewen could produce a
dark blue seedling by itself (i.e. self-pollinated), but it could if
pollinated by another tetraploid since it has Caesar's Brother in its
parentage.
Another possibility is that it is a cross of Ewen by a diploid's pollen (or a
diploid by Ewen or other tetraploid pollen). My friend Darrell Probst says
that sometimes tetraploids can cross with unreduced diploid pollen or ovules.
So what does unreduced mean? [not being a scientist this is my
understanding] In meiosis the last stage is the splitting of chromosomes
into haploids cells for joining with other haploids. Sometimes a tetaploid
can cross with a diploid which for some reason has not reached the reduced
haploid state and therefore create a tetraploid.
Looking forward to seeing it someday. Marty Schafer
