Eupatorium altissimum

Tall Boneset 

Despite the name, I have never seen this plant get as tall as the other members of the “boneset” genera, such as hollow joe pye weed; then again, I’ve only ever seen this species thriving in a few places, Dry prairies in Oklahoma, prairie restoration sites that resemble old field succession, and true locations of old field succession. (This speaks to me as a sign that i’m lacking visiting other prairies and true prairie remnants.) Anywho, the posts that @geopsych has been posting recently has me dwelling on summer. It makes upset at the lack of Asteraceae knowledge that plagues me and so many of my fellow plant enthusiasts. Right now i’ve been really loving the fringlet tribe in the Asteraceae: aka  Eupatorieae and have been trying to get more acquainted with the natives of Ohio that I felt like I was overlooking.The main group of Eupatorieae that I seem to miss has to do with the small window of time between peak forbe bloom of July and Goldenrod and true Aster season of mid August to September. This gem is one such example, It’s not very showy or bright but when all you have is sepia shades and Chartreuse blend greens during this time period white seems to really ‘pop’ on the landscape. As you can see in the back ground the majority of grey coneflowers were long done, and the vervain and goldenrods were just beginning to add some other colors to the landscape. 

Tall Boneset can be differentiated from the other few native white bonesets by its smooth leaf margins and plantain like parallel venation. The earlier white boneset has classic perfoliate opposite leaves with lobed margins; The phyllotaxy follows these opposite leaves alternating sides, opposite decussate. The later white bonset, or late blooming boneset, has lobed margins as well but they are petiolate like the tall boneset.

Eupatorium serotinum

Late Blooming Boneset

There is a bit of discrepancy in what to call these leaves, petiolate serrate or petiolate lobed, one thing is for sure and that is you won’t miss this species when it blooms. I don’t think there is often much out besides Spiranthes and Gentians in late September when this species is in bloom. I do still see the occasional goldenrods hanging on; but, most things are working on setting seed.

Ageratina altissima

Tall White Snake Root, False Boneset. 

More of an open woodland and shade plant is this species in the boneset tribe, Eupatorieae. Although most people who know this plant wouldn’t confuse something that seems more like mist flower in habitat for a boneset it still gets confused by the general public. This species is usually much shorter than normal bonesets and has much wider leaves overall. It is incredibly common along edge habitats in the midwest as well as open forrest floors. If you’re looking for a good nectar species for skippers and bees during the intermittent period of time between peak forbe and goldenrod season I would recommend this plant.
