Vernonia noveboracensisAlso known as:
New York ironweed,
Stunning for its height and the profusion of flowers it produces, Vernonia noveboracensis can exceed 6'. It is a robust plant -- hence the common name 'ironweed' -- that bears large terminal clusters of fluffy purple flowers. The deep-green leaves are lance-like and add an ornamental value to the plant when not in bloom.
Vernonia noveboracensis does very well in a wide variety of soils, including poorly drained ones. It is perfectly adapted to typical garden conditions, in full or part-sun. Because of its size, it is best planted in the back of a flower bed where it will provide a colorful backdrop in late summer through early fall. The height of the plant may be controlled by cutting it back hard in late spring. This will also promote the growth of additional flowering stems. Self seeds readily. Blooms August and September. Zones 5-8
Propagate by dividing mature clumps in early spring, or from softwood cuttings in late spring. Collected seeds should be sown immediately or they will require cold stratification.
The common name ironweed, might be attributed to the rigid, tough stems of the plant, as well as the rust color the flowers take on as they fade.
