Joe Pye Weed

Additional Information:

Scientific Name: Eupatorium fistulosum (Eupatoriadelphus fistulosus)
Common Name: Joe pye weed
Family: Asteraceae
Locale: Equinox Botanicals
Specific Region: Rutland, Ohio
Description: Close up of the individual flowers (florets) of Eupatorium fistulosum. If you look closely (these photos can be magnified), you can see there are around 4-7 florets per involucre (flowerhead). If it were E. maculatum it would have 10-16. This is an easily ascertainable characteristic. Pluck an individual involucre (consult botany books on the Asteraceae to learn terms) and roll it in your fingers gently and you should be able to count the individual flowers
