Yah, I love these flower too. We call it Kemuning. My friend said it is also called Qiu Li Xiang (9 Miles of Fragrance) in Chinese. I have one pot growing in the garden. Recently it gives out blooms profusely. I guess it's becoz of the intense heat. The fragrance is intoxicating, esp in the evening. It also attracts lotsa moths to my garden! Love it!
