Not exactly sure what the purple/purple white flower plants are/were.... got there a skosh late and missed the id
They are about 3-5 feet tall and and have multiple stalks coming from a central base. They can self pollinate so if you go pull some make sure they are in a bag, otherwise you could just be spreading them further. They were very identifiable, nothing else out there that looked like them. Assume they'll flower for another week or so...
