August brings not just the Susans, but also Joe – as in Joe Pye Weed (Eutrochium). Note that Joe Pye Weeds used to be Eupatoriums, but now thanks to the ever-busy taxonomists they are Eutrochiums. This is arguably an improvement since Eutrochium is one syllable shorter. (I’ve written my Senator demanding passage of a bill barring taxonomists from introducing new genus names with more syllables than the old ones. I should hear back any day now, though I can’t imagine what’s taking so long.)
Of course, Eutrochium has that belligerent hard C, while Eupatorium has a gentler sound to it. So I don’t know.
