When I saw the flowers, my first thought was Lilac Tasselflower (Emilia sonchifolia) because we have a lot of it growing around our yard but upon closer look at the leaves, I realized it's not Emilia. It looks so familiar and I'm sure an easy one for identification but I'm drawing a blank. It's breezy outside so these aren't the best shots but I hope someone can refresh my memory with a name.
