Description
Depending on the growing conditions, Rudbeckia hirta is usually a short-lived a perennial. But they are also prolific self-seeders, if you allow the flower heads to mature.
The foliage forms a rosette of furry leaves at the bottom, while the flowers tower 2 to 2.5 feet above.
They’re easy to grow and make a cheerful addition to the garden and an excellent cut flower.
Bees, butterflies, and other insects enjoy the flowers’ nectar. They’re a favorite flower of Carpenter bees, Leaf-cutter bees, and Green Metallic bees. They’re also a host plant for caterpillars for Silvery Checkerspot and Bordered Patch butterflies. Birds often dine from the mature seeds.

Tips for Growing Rudbeckia hirta
Start in cell trays up to 7 weeks before the last frost date and keep in a warm environment. Cover very lightly, as seeds need light to germination. Mist regularly to keep soil moist and avoid displacing seed. Once true leaves have developed, harden off before planting outdoors.
Black-eyed Susans can also be sown directly in the fall, at least two weeks before the first frost date. Surface sow and keep soil moist until germination occurs.
Plant in full sun or partial shade once seedlings are hardened off. Plant in sandy to average soil at least 12 inches apart and keep the soil moist until the plant establishes.
Once established, Rudbeckia is drought tolerant and requires no fertilizer.
Deadhead regular to increase blooming. For cut flowers, harvest before blooms are completely open. For dried flowers, cut when flowers have opened completely.
