Hibiscus Syracuse....lovely September flowering shrub, abelias (Confetti is a variegated gem of a plant), and, although quite tender, how about cannas? Verbena bonariensis will flower to the frosts. Ceratostigma and caryopteris will provide good blues in late summer as will the autumn gentians. Japanese anemones will provide colour up,to late summer but their invasive "qualities" make them undesirable for me. Try instead Anemone Wild Swan.
For me late summer and autumn provide masses of colour.....masses to choose from
