Rudbeckia is full of color for a long period of time. Keep it deadheaded, and plants can bloom for months. That, coupled with its height and easy disposition, practically guarantees its popularity. Rudbeckia fulgida is a no-fail perennial performer with several popular varieties, including ‘Goldsturm’. It is hardy from Zones 4–9. Rudbeckia hirta, also called gloriosa daisy, has attractive reddish brown color on its petals. It is hardy from Zones 3–7, but individual plants are short-lived. Fortunately, they readily self-seed replacements if there is any bare ground to be had.
Good companions include: purple coneflower (Echinacea purpurea), salvia, upright sedum, helenium, coreopsis, heliopsis, Joe-Pye weed (Eupatorium spp.), Russian sage (Perovskia atriplicifolia).

Rudbeckia is a tough prairie plant that succeeds without a lot of help. It can take inferior soils—including heavy clay—and deals well with drought, but it does require good drainage. Rudbeckia prefers full sun, but continues to flower in part sun. Powdery mildew sometimes affects foliage late in the season in humid weather. At that point, it’s easiest to simply cut the plants down to the ground and dispose of the debris.
