Lantana -"Landmark Sunrise Rose" - It starts yellow, then matures to coral then pink! So easy to care for, and butterflies and hummingbirds love it! More importantly, it can survive drought conditions!
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 the pot and you can fill it with many days worth of water, even in hot weather.
