Ironweed identification

Asked September 16, 2020, 5:20 PM EDT

I have a native plant that I believe is Ironweed. That said, I am having great difficulty identifying what type of Ironweed. I also have found more than one botanic name for Ironweed to add to the confusion. I have seen it as Vernonia and Veronia. The New York variety has smoother, thinner leaves and the Tall variety doesn’t have the serrated edges. That’s if this is Ironweed. Can you tell me what this wildflower is please? Also can you provide me with information on the varieties of Ironweed found in this area. Thank you, Stephanie =

This is not ironweed but instead is called blue mistflower (Conoclinium coelestinum).

The genus name for ironweed is Vernonia. Three species of Vernonia are recorded in Maryland and you can view photos of them here,

New York ironweed (Vernonia noveboracensis) is the native species that is most prevalent in Maryland, typically in moist meadow areas.
