Star Jasmine (Jasminum multiflorum), also known as Confederate Jasmine, is another plant that seems to like it here on the Gulf-coast. This perennial vine has lovely green foliage all year round, and is covered in snowy white flowers in the spring. Here's a picture of how mine looked during its last blooming season.
It is relatively low-maintenance, assuming you don't plant it someplace where you'll have to trim it back all the time. During the summer and fall growing season, it grows very rapidly. I have one that was planted underneath some trees, before I moved into my house, and I have to frequently trim it back to keep it from climbing into them. Star Jasmine can also work as a rambling groundcover, if you have a large enough space for it.
Here, it blooms in the spring. In the milder climate of my native Southern California, the star jasmine blooms into summer.
The only other difficulty I have had with mine is the occasional bit of powdery mildew, when the humidity starts to go back up toward the end of Spring.
I find, however that this is relatively easy to cope with, using an organic fungicide spray.
