Rudbeckia maxima (Giant Coneflower) is a striking, tall herbaceous perennial prized for its bright yellow, daisy-like flowers from mid-summer to early fall. This late-blooming coneflower produces large blossoms, up to 3 in. across (7 cm), with broad, drooping, golden-yellow petals surrounding a prominent dark brown central cone that may reach 2-6 in. tall (6-15 cm). Rich in nectar, the flowers attract butterflies and other pollinators, rising on sparsely leaved stems above a bold clump of large, smooth, blue-gray leaves. In fall and winter, the decorative seedheads extend the plant’s season of interest and provide food for visiting birds. Native to moist, sunny prairies, meadows, pastures, and fields in Texas, Louisiana, Arkansas, Oklahoma, and South Carolina, Giant Coneflower is an easy-going perennial that tolerates light shade, heat, occasional drought, and a wide range of soils. It is excellent at the back of sunny borders, in cutting, pollinator, or cottage gardens, and in meadows or naturalized plantings.
