Officially, blue vervain likes wet soils, but it's been growing in my dry, sandy hellstrip by the street for a few years.  It doesn't get quite as tall there, but it still thrives.  This is a nice plant to add some height to your garden.  The delicate purplish flowers attract lots of pollinators.  In my garden it seems like it grows somewhere just a little different each year because it readily reseeds itself and spreads, but it isn't aggressive.
