Who doesn’t adore black-eyed susans (Rudbeckia spp.) for their non-stop flowering and strong constitutions? Most cultivars sport bright shades of yellow and gold but tender varieties come in coral, rust, bicolors and even red. If you’re looking for long-lasting summer color to cheer you up, rudbeckia will do the trick.
Black-eyed (and brown-eyed, and green-eyed) susans are also commonly called coneflowers, a name that can refer to echinacea as well. To avoid confusion I’ll just call it rudbeckia here.
