Summary
Silphium compositum, commonly known as Kidney-leaf Rosinweed, is a deciduous perennial herb native to open woodlands and prairies of the southeastern United States. It typically grows to a height of 3-6 feet (0.9-1.8 meters) and spreads 2-3 feet (0.6-0.9 meters) wide. The plant is characterized by its large, kidney-shaped basal leaves and tall, sturdy stems topped with bright yellow composite flowers that bloom from mid-summer to early fall. The flowers are quite showy and attract a variety of pollinators.
Kidney-leaf Rosinweed is valued for its striking foliage and cheerful flowers, which add a splash of color to wildflower gardens, meadows, and naturalized areas. It is a low-maintenance plant that is drought-tolerant once established and thrives in full sun to part shade. It prefers well-drained soils but is adaptable to different soil types. While not commonly used in formal garden settings, it can be an excellent choice for restoration projects and pollinator gardens. Potential problems include occasional leaf spots and rusts, but these are generally not severe. It is not known for aggressive roots or significant disease issues.CC BY-SA 4.0
