Giant Coneflower, Great Coneflower, Giant Brown-eyed Susan, Cabbage Coneflower
Rudbeckia maxima (Giant Coneflower) is a tall herbaceous perennial boasting bright yellow daisy flowers from mid-summer to early fall. This late flowering Coneflower features large daisy blossoms, 3 in. across (7 cm), with broad, drooping, glowing golden petals surrounding a prominent dark-brown center cone that can reach 2-6 in. in height (6-15 cm). Attractive to butterflies and pollinating insects, the blossoms rise atop sparsely leaved flower stalks above a mound of large, smooth, blue-gray leaves. Its attractive seedheads further extend its season of interest and will be visited in the fall and winter by birds that will feast on them. 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, some drought, and a wide range of soils. Great along a sunny border, in a cutting, pollinator, or cottage garden, or in a meadow or naturalized area.
