Rudbeckia laciniata (Cutleaf Coneflower) is a rhizomatous perennial boasting bright yellow flowers from mid-summer to mid-fall. Very tall, this late flowering Coneflower features large daisy blossoms, 3-4 in. across (7-10 cm), with broad, drooping, glowing golden petals surrounding a prominent pale green conical center that turns brown as it matures. Attractive to butterflies and pollinating insects, the blossoms rise atop wiry stems above the deeply-divided foliage of light green 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. Cutleaf Coneflower spreads rampantly by underground rhizomes and is only appropriate for large landscapes.

• Grows up to 3-9 ft. tall (90-270 cm) and 2-4 ft. wide (60-120 cm). Can spread aggressively by underground rhizomes.
• Performs best in full sun or part shade in average, moist, well-drained soils. In shade or under dry conditions, the plant tends to get leggy and flop, so it may require staking to hold it upright. Tolerates wet soils and seasonal flooding.
• Great at the back of borders, in cottage gardens, or in prairies and meadows.
• No serious pest or disease issues. Deer resistant.
• Deadhead spent flowers to encourage additional bloom. Cut back in autumn. May need staking
• Propagate by division in spring or autumn. Divide plants by separating rhizomes in spring or late autumn.
• Native to North America.
