Hey, what happened to those yellow genes?

This Angel Trumpet cross involving the double white brugmansia Sweetheart and the single bright yellow/orange Herenhauser Gold just opened last night. 

This is the first seedling from this cross to bloom and I know I have more out there in waiting.  Hopefully at least one of them will display the best genes of both; Sweetheart's form and durability with the color of Herenhauser Gold.
