These perennials usually remain in the 1 to 2 feet high range under most conditions. They are still low enough for the front of perennial border, garden, and landscape and some of the rhizomatous species will make low to medium height groundcovers. Their tidy habits also lend them to use as fillers and spillers for container specimens and in combinations for small to medium sized containers. Growing conditons and how well a plant is established may affect it's ultimate size.
A 2020 All American Selections Herbaceous Perennial award winner! 2-3" wide dark-eyed golden yellow daisies are produced throughout the summer and even into fall atop a dense and compact well-branched plant. American Gold Rush Rudbeckia was selected with disease resistance in mind as well as this plant's ability to flower throughout summer and a compact habit. It may be most similar to and is considered to be a hybrid of Rudbeckia fulgida var. deamii, or the Brown-Eyed Susan, which can reach 3' in height. Like its parent, expect this hardy clump forming perennial to revel in the heat and sun of summer with its disk flowers providing nectar for smaller pollinators and the ripened seeds of fall and winter are sure to attract songbirds. Provide American Gold Rush Rudbeckia with a full to mostly sunny site in an average moist, well-drained soil for optimum vigor and flowering. Add this easy to grow perennial to the garden and landscape but it is also compact and free-flowering enough to provide a summer long show as a container plant.
