Abelia is s very attractive and useful plants! At first I thouhgt these flowers look very much like jasmine. But in your comment section there are so many different photos including the pink varieties!
I am going to investigate whether I could find this plant in Thailand. These can become fence as well!
Thank you for all your effort and sharing these valuable information. You have set up a database for me!
Cheers.
I'm happy it is useful to you !!
