Recently I wrote about Firebush, Hamelia patens, a great summer shrub. Today, it’s Brown-eyed Susan, Rudbeckia triloba, a tough summer flowering plant with a profusion of sunny yellow blooms.

Many more blooms

This plant is different from the Black-eyed Susan, Rudbeckia hirta, in that it has many more blooms of smaller flowers that usually have fewer rays per flowerhead.

Native to North America

It’s native to North America and is described as an herbaceous perennial (dies back in winter) that is hardy in Zones 4 – 8. Wakulla County is USDA Zone 8b and 9a along the coast. The R. triloba (and R. hirta as well) loves full sun, defined as at least 6 hours of direct sun and does very well in my yard with 10+ hours per day. It is heat and drought tolerant, however does best with regular watering. It is somewhat resistant to deer and has no serious pest or disease problems.

Master Gardener: Brown-Eye Susan imageNative, NOT invasive

This is an enthusiastic reseeding plant! Since it’s native, it’s not defined as invasive, but I would strongly encourage very active management of the seedlings when they appear in the spring.

Attractive clump

As you can see from this photo, I did not eliminate enough plants that came up and they’ve taken over this bed. They start out so small and develop into an attractive clump. Then they really take off! They transplant easily, so dig up the extra, put them in pots and share them with your friends and neighbors and be sure to let them know there is a no return policy.
