Any ideas why my Rudbeckia's are curling up and dying like this?

Some annual and biennial rudbeckia species simply fade away after they have completed their life cycles. Might this be the case with the one shown in the photo?

If disease hastened its demise, we'd need to see what the plant looked like before it succumbed to diagnose the problem.

This species has been in this area for quite some time. This seems different than before. The same plant species in other areas of the yard currently is flourishing. On the other hand, it could just be that I am not ready for our season to come to an end...Thank you for your time.

Most rudbeckias self seed readily, especially native species. Left to their own devices, they come and go constantly in a rhythm dictated by weather and growing conditions. However, they are subject to a number of diseases that can shorten their lives, powdery mildew being one of the most common.
