Vernonia noveboracensis - New York Ironweed
New York ironweed is a tall, clump-forming perennial, growing 5-8 ft. in height. Slightly rough stems bear lance-shaped, deep-green leaves. Small flower heads occur in large, loosely branched, flat-topped, terminal clusters. Flowers are all of the disk type and deep reddish-purple in color. Tall erect stem branches toward the summit, with each branch bearing a cluster of deep lavender to violet flower heads; together, clusters form a loose spray.This often roughish plant is common in wet open bottomland fields. It typically has more flowers per head than Tall Ironweed (Vernonia gigantea).
