I love the way this plant naturalizes here in zone 5. It makes a beautiful statement when planted in mass!

Rating for this plant:
I have two kinds of rudbeckia. One blooms early in July, the other in late July and August. Both self-sow prolifically (ie even in my lawn). I just yank them out where I do not want them. There is something about them that is so quintessential summer, that they are well worth the work of weeding them out.

Rating for this plant:
The ones I have are Rudbeckia Hirta 'Becky' or Cinnamon. Some of them are different as I start them from seeds. They are very, very easy to grow here for zone 6. I just throw the tired blooms out there somewhere amongst the weeds...and out there they are. Prolific bloomers and the plants do look very tired after blooming non stop..then I'll cut them down to the ground. Even when I don't have the time to water them sometimes, they're still quite drought tolerant. They don't seem to like the pine needles here. Perhaps, too acidic.

I like this opinion
