Vernonia fasciculata, commonly known as Smooth Ironweed, is a tall, native perennial wildflower found in prairies, wetlands, and along roadsides throughout Illinois. It thrives in moist to medium soils and prefers full sun, making it an excellent choice for rain gardens and pollinator-friendly landscapes.
Growing 3 to 5 feet tall, this plant is known for its striking clusters of bright purple flowers that bloom from mid to late summer. It is highly attractive to butterflies, bees, and other pollinators, while its seeds provide food for birds in the fall. Its strong stems and lance-shaped leaves add structure and visual interest to natural plantings.
For Illinois native plant enthusiasts, Vernonia fasciculata is a valuable addition to prairies, meadows, and wetland restorations. It pairs well with other native perennials like Goldenrod, Joe-Pye Weed, and Big Bluestem, creating a vibrant, wildlife-friendly habitat. It is also drought-tolerant once established, making it a resilient choice for a variety of landscapes.
