Columbines will grow just about anywhere. This isn't the same as saying they grow everywhere. Here is one of ours that grows in the corner of a flagstone step.
They don't appear to have a scent, by the way.
This is my favorite color combination: purple and yellow. We have just the one plant, right by the downspout out front.
There was a very nice red and white columbine growing out of a rock next to the driveway, but it was lost when we had to replace the steps. I'm going to see if I can buy one and get it to grow there again.
