How To Use Black-eyed Susan In The Garden
Black-eyed Susan (Rudbeckia) produces long-lasting golden blooms that appear from mid-summer through the first frost, lending a bright note to perennial beds. The fuzzy foliage discourages deer, while the seed heads support local bird populations in fall and winter. This easy-care native tolerates a range of soil types and returns each season, sometimes spreading by self-seeding. Its cheerful daisy-like blooms complement a warm color palette and draws bees and butterflies.
Plant groups of black-eyed Susans in sunny borders or naturalized meadows for warm seasonal color. Combine them with ornamental grasses and other mid- to late-season perennials for an appealing tapestry of heights and textures. They also work well in pollinator gardens, where their nectar and seed heads benefit insects and songbirds. In containers or near a patio, these hardy blooms introduce an inviting touch of summer to gathering areas.

Black-Eyed Susans Care
Plant Black-Eyed Susans in full sun and well-draining soil. They tolerate various soil types, including clay and sandy soils. Water young plants regularly to establish a strong root system; once established, they are drought-tolerant. Fertilization is generally unnecessary; however, applying compost as mulch can enhance soil fertility.
Deadhead spent flowers during the blooming season to encourage continuous flowering and prevent unwanted self-seeding. In late fall, cut back dead plant material to ground level to prepare for winter dormancy. Black-Eyed Susans can be grown in containers with good drainage; use a well-draining potting mix and water when the top two inches of soil are dry.

Black-Eyed Susans Companion Plants
Give companions a position with six or more hours of sun, moist yet free-draining soil, and low fertility so black-eyed Susans keep their tidy clumps. Red twig dogwood brings winter bark color and a reliable green backdrop, while Russian sage cools the scene with airy blue wands that bloom alongside the daisylike discs. Agastache extends the nectar buffet into late summer, and a drift of yarrow supplies texture and seed heads that echo Rudbeckia’s own autumn silhouettes.
