Saturday Photo: The Beauty of Invasive

Maybe 20 years ago I bought a couple of columbine plants at a time when I wanted to switch to annuals in our small garden.  They have thrived, and are now in bloom  in front and in back of our house...and also in several other yards along our street.

I've done a little selective transplanting, but never onto to neighbor's property, so it would appear that at the force that through the green fuse drives the flower (to quote Dylan Thomas) has spread these lovely, complicated flowers.

Does this make them "invasive?"  Perhaps.  If so, what a lovely kind of invasive plant.
