Growing Guide & Production Protocols
Cultivation & Growing Guidelines
Rudbeckia, commonly known as ‘black-eyed Susan’, is a popular perennial known for its bold, daisy-like flowers with dark central cones. Native to North America, it thrives in full sun and well-drained soil, offering excellent drought tolerance and exceptional garden performance. Easy to grow with uniform sticking and rooting, thriving in well-drained media under moderate fertility. Typically low PGR use is needed, as plants naturally form strong stems topped with bold yellow to orange daisy-like blooms for long-season color.
Rudbeckia is widely used in pollinator gardens, mass plantings, and naturalistic landscapes, valued for its long blooming period, resilience, and vibrant seasonal color.
