* Required Fields



Rudbeckia subtomentosa, commonly known as Sweet Black Eyed Susan or Sweet Coneflower, produces an abundance of striking, yellow, 2" to 3" inch daisy-like flowers with bold chocolate brown centers on wiry stems. The flowers emit a mild scent of anise. Well formed plants of 48" inches feature toothed gray-green foliage with downy hairs and long slender petioles. This flowering perennial is easy to grow and loves a sunny location. In a wildflower prairie, it will self sow freely to naturalize in a season or two from original planting. This variety tolerates moist soil and is an excellent addition to stream sides, creek areas and boggy meadows. Notably the genus name honors Olof Rudbeck (1630-1702), Swedish botanist and founder of the Uppsala Botanic Garden in Sweden. Hardy to zone 4, deer resistant and heat tolerant. Great cut flower. Deadhead regularly to encourage new growth. Flowers from early summer through fall frost. Packet: 50 seeds.
