Yes, I have a hard time flowering the red variety. The white variety flowers profusely in a tiny pot all winter. I got to try an amazing jam made from the flowers but didn’t realize there was osmanthus wine!
EDIT: I also have an Aglaia plant @IL847 Do you know if this is edible? I’ve only known it as a dooryard ornamental, but the flowers smell like they’d be great in tea too.
