and it smells WONDERFUL!! It's on a terrace outside our guest room that I pass every time I go upstairs, I love that hit of scent as I walk by. It is a Tabernaemontana divaricata, which I think is Crepe Jasmine in English? The name in Spanish, Clavo de la India, translates to Clove of India.
Also on that terrace, though it has no smell, is a pot of plumbago which is looking really nice now. It's a really common plant from my childhood, my mother used it as a groundcover, but I'm really enjoying it as just a spot of blue.
