Sweet Perfume

I am not sure what this flower is, but the fragrance at dusk is hypnotic. I was taking out the trash, when this delectable smell wafted into my nose. The scent is so subtle, you don't really know where it is coming from. I had to smell every bush in the yard until I found it. I love discovering all these new plants and flowers...I really need a gardener. I don't have time to give them the proper attention. This yard, because it is a rental, has had better days, yet these flowers are still hanging on.....barely.
