To be honest I never pay much attention to the one planted in my yard, it was here when we moved here three years ago and I had my husband transplant it to a different location this past spring. I was told that it's Jasminum nitidum; it hasn't grown much in height since we've been here, staying at around 3 1/2 feet tall and 4 feet wide. It could be slower growing because of the location, it only gets a little water now and then unless it rains.
