Wild Flowers of Pittsburgh

Tall Ironweed (Vernonia altissima)

Vernonia-altissima

No photograph can convey the vivid purple color of ironweed, one of our most spectacular late-summer flowers. A field of ironweed and goldenrod is a sight not easily forgotten. Two species are common in our area; Tall Ironweed is, as its name implies, taller than New York Ironweed (Vernonia noveboracensis), but otherwise very similar.
