Wanting white on my deck!

I was really hoping for some winter white on the deck.

Here's some 'deck white' from another season.

I planted a moonflower vine at the corner post. Til the end of summer it had all but covered two sides of the deck. It was a prolific bloomer. Buds appearing everywhere in a corkscrew fashion and as the sun would set the buds would open and bloom during the night. As the morning sun hit them the next day the flower faded. But another one was waiting and ready for that evening.

The blooms were 5-6 inches across. I saved lots of seeds and hope to have more for this summer. But I hope I don't need to wait until summer for a white deck.
