Herbstonne is a great background plant. The foliage is always clean and nice looking.

During early years, it would sometimes flop over because it was so tall. I now cut it back about 6" when it's around 2-1/2' tall. That keeps it about 5-6' tall. Give it plenty of room.

Bees LOVE this plant.

This is a great, tall yellow accent for the garden with very hardy, vigorous growth. My plants have survived attacks by voles by increasing in vigor. Unfortunately, voles did consume one of the three that I had purchased and planted along the west side of my home. Rudbeckia 'Herbstonne' blooms late in the spring and into the summer. During years without oppressive drought conditions, there has been a rebloom period that extends the bloom time through most of the summer. I have received compliments on 'Herbstonne' from my neighbors, and they couldn't believe that they were a Black-Eyed Susans. Overall, a very satisfying tall perennial that adds the welcome promise of returning sunshine every year.

I love this one. It gets 7'+ & covered in yellow flowers with tall cones. Bugs don't bother it.
