I Have No Idea...
Which is not surprising if you have seen my myriad of flower photos over the years. I rarely know what they are, but whatever it is this one is pretty neat. I will call it a pineapple flower. Yeah, that sounds accurate.
Added at 7:27 on Monday: Dennis Mook tells me I need the “Garden Answers Plant ID” app where you submit a plant photo and you get the likely name back, in this case “Mountain Knapweed.” Dennis, my go to guy for photography now branching out to the world of biology. Although I still think Pineapple Flower is a great name.
