Blooming mainly in summer, black-eyed Susans (Rudbeckia hirta) commonly grow 24 inches tall with signature yellow to orange petals and a dark center point. Although the blossoms appear fragile, these perennials have a strong root system that often allows the plant to rejuvenate itself every year.

Does Rudbeckia grow back every year?

Do Rudbeckia grow back every year? Yes, they may be perennials but certain varieties are often treated as annuals.

What do you do with Rudbeckia in the winter?

If you don't like an untidy look in winter, you could cut them right down and mulch heavily over the top, a good couple of inches or more, with something like garden compost, bark chips, whatever, again for added protection. But don't forget to rake off some of the mulch in spring, as growth begins.
