Shear plants after blooming to improve appearance and create rebloom.This now-prominent plant in my garden arrived as a weed, blown in from 
around the neighborhood. But I’ve nurtured it, even helped it spread, because it’s a do-er. It looks gorgeous winding among the later-blooming perennials, and it blooms in a lovely pink when almost nothing else blooms in my garden. I can’t remember ever watering it.
Native from the Midwest south to Texas and Mexico.
