Please help identify this yellow double petalled hibiscus

Hello folks,

I'm new in this forum.

I'm identifying plants in our monastery, and I could use some help.

The closest in the Plant Files are "Saffron Moon" and "Full Moon".

Perhaps you could help.

Thanks.

Here's another shot.

Perhaps Butterball? :) ~Cheryl

Thanks very much, Cheryl. Looking at the PlantFiles, the leaves look right, but let me check again today.
