plant.jpgDoes anyone know what this plant might be? The honey bees seemed to like it. I have not seen one before.

Looks like wild sunflower to me.

It looks like it could be Cup-plant [Silphium perfoliatum] from the leaves on the far left side in photo. Do the opposite leaves completely surround the stem to form a small cup? It's a native [I think] prairie plant in WI. anyway.

possibly Woodland Sunflower (Helianthus Strumosus) or Prairie Golden Aster a.k.a. Hairy Golden Aster (Heterotheca Camporum). I bought a field guide to wild flowers my first year of beekeeping just so I could identify the flowers that were blooming in my area, it has proved invaluable to me over the past 6 years I recommend it for anybody keeping bees or wild crafting.

Thanks Oldbee.
This is the plant. This plant is at the nature center here in Knoxville. Looks like it is native to the eastern US. Cool plant.
