I love this idea for putting posts up, for lamps, that can also be fence or divider connectors. I like hiding a sturdier metal post inside a fabricated wood post, then attaching the remainder of the fencing to it. Great for high wind areas.
Horsetail and creeping jenny - very compatible, they both like it wet. This kind of plant combination is fairly easy to maintain because it doesn't need a drain hole in pot, you can fill it with many days worth of water, even in hot weather.
If I had to do an ugly chain link fence. Confederate Jasmine is an evergreen flowering vine, drought tolerant once established. It does not clump at the top, so would be ideal for covering a chain link fence year round.
