Asteraceae (Aster Family)



Vernonia baldwinii (Baldwin's ironweed)
Bransford, W.D. and Dolphia
Western ironweed’s 3-5 ft. stems occur singly or in clumps, and are stout and hairy. Wide clusters of vibrant, red-violet flowers form at the ends of short branches near the top of the plant. Because the flowers are all of the disk variety, the 6 in. wide flower cluster has a fuzzy appearance. Long, lance-shaped leaves line the stems.

This plant aggressively colonizes by rhizomes once established so place accordingly. Its bloom period lasts until frost.
