Summary

Rudbeckia laciniata, commonly known as Cutleaf Coneflower, is a deciduous perennial herb native to moist, rich floodplain forests, wet meadows, and along stream banks in the Eastern, Central and Intermountain region of the United States, as well as Eastern Canada. This species typically grows up to 3 meters (10 feet) tall and is known for its deeply cut, bright green leaves. The composite flowers, blooming in late summer to autumn, feature a prominent, raised central cone that is green to yellowish-green, surrounded by drooping pale yellow ray florets. The flowers are arranged in umbrella-like clusters, with each cluster containing multiple cup-shaped partial inflorescences.

Cutleaf Coneflower is valued for its tall, stately form and its ability to thrive in a variety of garden settings. It is especially noted for its long blooming period and its attractiveness to pollinators such as butterflies. The plant is commonly used in naturalistic plantings, as a background plant in borders, and for cut flowers. It is adaptable to a range of soil types, though it prefers moist, well-drained soils, and can tolerate both full sun and partial shade. The cultivars ’Herbstsonne’ and ’Starcadia Razzle Dazzle’ have received the Royal Horticultural Society’s Award of Garden Merit, and ’Goldquelle’ is celebrated for its double yellow blooms. While generally low-maintenance, it can be susceptible to powdery mildew and leaf spot diseases, and may spread aggressively if not managed.CC BY-SA 4.0
