Summary
Rudbeckia hirta var. pulcherrima, commonly known as Black-Eyed Susan, is a versatile plant that can be an annual, biennial, or short-lived perennial herb. It is native to open woodlands, prairies, fields, and roadsides across the Central and Eastern USA and Southern Canada. This plant typically grows to a height of 1-3 feet (0.3-0.9 meters) and a width of 2-3 feet (0.6-0.9 meters). Black-Eyed Susan has a clumping form with lance-shaped leaves, and it is renowned for its daisy-like flowers with a prominent, dark brown central cone surrounded by bright yellow to orange petals. The flowers bloom profusely from midsummer to early fall and are highly attractive to pollinators.
Black-Eyed Susan is valued for its ease of maintenance and its ability to thrive in a variety of conditions, making it a popular choice for wildflower gardens, borders, and naturalized areas. It is also used for cut flowers due to its long vase life. In cultivation, it prefers full sun to part shade and adapts well to soils with fast drainage, though it can tolerate clay soils. While generally drought-tolerant, it benefits from occasional watering during prolonged dry spells. It is relatively pest-free but can be susceptible to powdery mildew in humid conditions.CC BY-SA 4.0
