On the way to the bus stop

I love this flower, I have no idea what it's called, but it's so pretty. I'm sure what the German's call it and what we would call it are 2 different things. It's the prettiest color blue and grows on a bush that's taller than me. Lots of people have them here. But there is a lady that has about 6 of them in her front yard. I've been seeing hers since we got here, and since it's on the way to the bus stop I see them every day now. In fact that's where this picture came from. There has been flowers on them since we got here in June! Can you believe it? I believe I will try to plant one or two here next spring . . . that is if you can tell me what I should ask for!
