Vernonia glauca

Broadleaf Ironweed

Broadleaf Ironweed blooms in August and September, producing large showy clusters of deep purple flowers with fine petals.  Vernonia glauca is somewhat more compact than its cousin V. noveboracensis, and tolerates dryer conditions.  Hiding in the background for much of the summer, it really stands out when in bloom in late summer.  Butterflies cover the flowers, adding to the show.
