We think of autumn color in the leaves of shrubs and trees such as the sugar maples, which can be brilliant gold and with reddish tinges at their tops. Because of their size the color grabs our attention, however, many other plants also display dramatic changes in color when the green of chlorophyll is no longer being produced to mask underlying pigments. In the prairie the huge leaves of compass plants may also turn golden yellow nestled among the mature grasses and late fall asters. In this plant you can see the process is just half way completed. Keep watching and you will make new discoveries.
