Black-Eyed Susan (Rudbeckia hirta) or a closely related Rudbeckia coneflower species, captured at two distinct life stages:

• Foreground (Left): An unopened flower bud with soft green phyllaries (involucral bracts), developing yellow ray florets just beginning to emerge, and a tightly clustered dark central disc cone.

• Background (Right): A fully opened bloom showing mature bright golden-yellow ray petals radiating around a deep brown-purple central disc cone. (Narration - Gemini AI)
