I love this native plant, and so do pollinators. There are some little native bees that show up for this flower in droves, and it's great entertainment to watch them crash into each other as they jostle for position on the flowers.

I'm surprised it isn't grown more, it's so attractive and tall, and has a fairly long bloom season here. It isn't weedy here, but looking at its native distribution, it doesn't seem to be a coastal plant, so it might self-sow more generously elsewhere. (I grew my plants from a seed packet from Prairie Moon.)
