Vernonia missurica

Missouri Ironweed (Vernonia missurica) is a tall, upright perennial native to moist prairies and open areas, typically reaching heights of 4 to 5 feet. It features striking clusters of vibrant purple flowers that bloom in late summer, attracting butterflies and other pollinators. Missouri Ironweed thrives in full sun but can tolerate up to 20% shade, and it prefers medium to wet soils, making it well-suited for rain gardens or moist meadows. Once established, it is relatively low-maintenance, though periodic watering is helpful for young plants or during drought. This species is valued for its bold color and ability to provide structure in native plantings.
