One of the nice things about where this tree is situated is that the background is a hundred yards away. That allows for good blurring of the background in most cases. A redbud tree in the background lends pinkish highlights.
By shooting either early in the day or late in the day, specular highlights can be included in the background as well as some warmth of color.
I personally like the backgrounds where a pattern can be included such as in this image.
