The Rudbeckia in this charming combination with the Aster novae angliae, would appear to be a Rudbeckia triloba, a biennial, rather than the Rudbeckia fulgida var. sullivantii 'Goldsturm'. Rudbeckia triloba has a much tinier blossom than the Goldsturm blossom, and has a bloom time that matches the timing for the Aster novae angliae.
It still makes a very beautiful Multi-Plant photo!
