Axel,
Thank you for sharing the photos,
Looks like it has the roundness potential.
What is the size of the flower for this first bloom?
Do you have the parents' clone names?
Hien, this bloom was (it flowered in June-July actually) 12.5 cm wide. Not very big, but it could improve I think.
I don't have the clonal names of the parents.
Bite me! A unanimous comment from us in the US? Great job Axel!!! Folks, please keep posting pix of your Viet-Paphs! We don't get to see them otherwise.
