Which solar term does osmanthus fall in?

Osmanthus fragrans appears in people's leisure time. Osmanthus fragrans usually blooms from mid-August to September, so it is said to be in autumn. But because the night before was quiet and the mountain was empty, there was a contradiction, but according to the national textbook, most of the answers were autumn!

Hope to adopt! But you have to confirm it yourself!

Thank you (*^o^*)!
