About Missouri Ironweed

Missouri Ironweed is a robust and adaptable perennial that brings a touch of wild beauty to the midwestern landscape. Growing 3 to 6 feet tall, this species is characterized by its slightly hairy stems and broad, lanceolate leaves with fuzzy undersides. From July through October, it produces dense, showy clusters of deep purple flowers that are a favorite of long-tongued bees and butterflies alike. Native to the central United States, Missouri Ironweed is often found in moist prairies, meadows, and open woodlands, though it is notably tolerant of both wet and dry soil conditions once established. This versatility makes it an excellent choice for a variety of garden settings, from rain gardens to drier upland borders. It performs best in full sun and can tolerate periodic flooding, making it a resilient choice for challenging sites. Like its relatives, Missouri Ironweed is a reliable source of late-season nectar, ensuring your garden remains a hive of activity well into the autumn months. Seeds should be sown in the fall for natural stratification.
