LOVE the colors in that hibiscus!
Super cute bike, and a great first attempt at planting. I see nothing wrong with it, but if I wanted to rev it up next year, I would think about fireworks pennisetum to echo the pink and maybe combine that with purples and chartreuse/light green foliage --coleus or potato vines. And perhaps just a hint of a pale yellow. I would like some stuff hanging down and draping the bike a bit. And I might use brightly colored pots too. But that's my taste and my guess, and I never know if I chose the right stuff until afterwards
