Aww, I'm almost a grandmother ;-)

Don't forget, "cloud shadows" also gives pink or yellow seedlings in the
right kind of cross. I've gotten a few pink or yellow amoenas from some
of its siblings, but haven't had the right kind of crosses to know if it
can produce them as well.

Attached is a seedling from "cloud shadows" X DIGNITY DANCER, showing
the strong yellow it can produce. In a variegata pattern. And a pink
seedling from an experiment with a cross using a weedy, very retro,
muddy looking yellow bee seedling from PINK FORMAL.

>From the pedigree, looks like the MTB cross might give you some of the
super floriferousness (is that a word??) that you want.
