Frostweed (Verbesina virginica)

I hope the ID is correct. Verbesina virginica is definitely found in Jonathan Dickinson State Park. The stems are winged and the leaves of the above plant were deeply lobed (parted). In most references and photos I've seen, this species has ovate or lanceolate leaves. Apparently, really big plants develop these lobed leaves. This aster is gigantic, nearly 6 feet tall. It was impossible to get a shot without a pollinator as this is a very popular, trendy eating spot with a long waiting line (apologies to the anti-buggites). This plant was so tall and the surrounding brush so thick that I couldn't get the entire thing into a photo. It gets it's frosty name from the peculiar habit of exuding water from the stems during freezes, forming all sorts of bizarre ice shapes. According to Dr. Austin in Florida Ethnobotany, the Seminole people made extensive medicinal use of this plant to treat a range of health problems including "bear sickness", "mist sickness", "fire sickness" and stomach ache.
