Three-lobed Coneflower (Rudbeckia triloba) is a knockout in the late summer landscape with its showy floral display of bright yellow flowers. Like other Rudbeckia species, Three-lobed Coneflower is very drought – heat – and pest-tolerant. It’s an excellent choice for rock gardens, banks or other drought-prone sites. Native to the United States, Three-lobed Coneflower is well-adapted to poor soils and requires little care. It’s an exceptional perennial for the low-maintenance gardener.
Prefers sandy or loamy, moist soils, but is drought resistant. Spreads slowly by rhizomes. Deadhead to prolong blooming season. Propagate by seed, cuttings and division. Cut back to the ground after first frost and mulch to protect roots for the winter. Outstanding in mass plantings, as a border perennial, or in rock or low maintenance gardens.
