Dahlberg Daisies are back

One little pot of these plucky Dahlberg Daisies has kept us in flowers for at least three years now. They apparently seed themselves, and each spring since we bought our first pot full, they've popped up between the flagstone pavers. We don't like weeds growing between the stones, but these are too pretty to take out. Each clump grows from one root and now that we know how prolific they are, once they quit blooming they're "outta here"...well, at least until next year.
