It's difficult to tell the difference here, Sandy, I know, but the tall yellow and purple-blue flowers in the last set of pictures are actually my preferred plants!
Maybe that's part of my planting and viewing strategy, eh? A naturalistic look that defies being categorized! One is never entirely sure if what's being viewed is supposed to be there!
I'm glad that you saw them as pretty flowers, because that's how I see them, too.
