Sorry... I don't have a photo. But I've been seeing it at two houses on my commute. The flowers remind me of either Petunias or Morning Glories. At first I thought it was just morning glories growing over a shrub, but the flowers are there in the afternoon too. And they appear to be actually blooming from the shrub. I've been tempted to stop and either get a photo or ask the owners... but it's not in a very good part of town and I'm not comfortable just knocking on the door. Does it sound familiar?
