Ken -- You are way too modest. Yes a historical plant. Seed to bloom in 15 months!! And then - of all the plumeria you have grown over the years, it is also the first to set seed. Quite historical.
Reviewing the flower form and scent, Ken have you ever guessed who was the pollen donor?
BTW - where did you get the seeds?

About how long did it take for germination?
I have mine on a heat mat set at ~ 80 F.
Note that at this point, I only have 6 seeds
