I love it every spring when my small bunch of red columbines, Aquilegia canadensis, blooms.
These are volunteers from who know where, and they decided to grow hugged up against the corner of the house far out of regular view. They thrive in alkaline soil, so perhaps they benefit from the cement skirting around the base of the house?
I've been tempted to transplant these to someplace I want them, but always decide they are better off where they want to be. And it doesn't take much effort for me to visit with them in their place anyway.
