update that interests prolly me only! an "anonymous" user commented on another site where to find the picture i was after...and now i need to get my memory checked...
here is the gigantea x Sogo White that user Sade2020 posted here on 5-5-22
as you can see, it is identical to our seedling. so, what i thought was a seed grown cross im now thinking may have in fact been some clones. for sure i deflasked them myself, but i don't know where they originated. the flowers are just too similar to me.
