Several people asked about the name of this flower (which is also called jewel weed). As best as I can tell it is simply because the ripe seed pods are under considerable pressure, and will pop open at the slightest touch spraying the seeds all over any one standing nearby. In reality this is a useful evolutionary device -- getting passing humans and animals to carry one's seeds far and wide at the slightest touch. So from the plants point of view their name ought to be "touch me please!"
You can see some of the (not yet ripe) seed pods near these flowers.
