That's not a bad idea at all Ken.
My second Yugumbah Spirit seedling is eerily similar to the first one except it has a hint of pink, which might disappear once it is fully opened.
now I have 2 yellow in my plumeria collection. The fragrance is similar to the first too...jasmine fragrance. Looks like the pollen parent must be a dominant yellow. This has generous branching -4 tips and it is a 3 feet tall seedling.
