I have a free-standing metal frame covered with a rattan awning on my terrace that serves as a shady shelter for my outside table and chairs. It's functional, but rather unattractive. So this year I planted morning glory seeds in big pots next to two of its legs.
The vines have twined nicely up the support poles and I actually have a few blooms.
This, however, is more the look I was going for. Sigh...maybe next year?
