| Maintenance | Need loppers to cut back the thick, dead stalks in the fall. A sweet fragrance will be emitted from the cut stems. Will self-seed all over the garden. |

| Native Site | Native North American prairies, Wisconsin |
| Author's Notes | R. subtomentosa may open up in the center. To hide or prevent this plant a few closer together. I like to plant these behind Rudbeckia Goldstrum. They start to bloom after Goldstrum and the yellow color works with Goldstrum's golden-yellow. I have mass planted this Rudbeckia and during fall clean up you can really smell the fragrance of the plant. |
