Vernonia fasciculata

Scientific Name: Vernonia fasciculata

Common Name: Ironweed

Exposure: Full sun

Blooming Time: July to September

Bloom Duration: 6 to 8 weeks

Fragrance: No noticeable fragrance

Plant Growing Habit: Upright, clump-forming

Characteristics: A tall, North American native perennial with sturdy stems topped by dense clusters of vibrant purple flower heads that provide outstanding late-season colour. Its lance-shaped green foliage remains attractive throughout the growing season. An exceptional nectar source for bees, butterflies, monarchs, and other beneficial pollinators. The seed heads also provide food for birds in autumn and winter. Ideal for native plant gardens, pollinator gardens, meadows, rain gardens, and naturalized landscapes.

Spacing: 60 to 90 cm apart

Height: 120 to 180 cm

Width: 60 to 90 cm

Maintenance Requirements: Low maintenance. Prefers full sun and moist, fertile, well-drained soil but adapts well to average garden soils once established. Water regularly during the first growing season to establish a deep root system. Once established, it tolerates short periods of drought but performs best with consistent moisture. Cut back stems in late fall or early spring before new growth begins. Staking is generally unnecessary due to its strong stems, although plants may benefit from support in very windy locations. Fertilization is rarely required. Hardy and well-suited to Canadian gardens in Zones 3–8.
