Jonesboro Giant ironweed is a form of a perennial plant that is native to the eastern parts of the US where it grows in locations that are consistently moist. It bears large bracts of smallish bright purple flowers in late summer to mid-fall providing an unusual pop of tall color in the late season. Jonesboro Giant grows to a height of about twelve feet and a width of about five feet in sunny conditions, and slightly less in shadier spots. It can become weedy, so care should be taken in siting it, and removing unwanted shoots. In an evaluation of ironweeds conducted at the Chicago Botanic Garden, Jonesboro Giant ironweed received a good rating for growing in local conditions.
