Hagoromo Japanese Joe Pye Weed. I found this finely cut leaf Eupatorium in one of our favorite hunting grounds, Ishiguro Nursery near Nagoya, Japan, during one of our visits in the fall of 2010. The foliage alone attracted me to it with its extremely finely cut leaves. Then the owners son-in-law showed me one in flower. It had soft pink flat (cyme) terminal flower heads on the top of each stem. Really outstanding! The cultivar name 'Hagoromo' refers to one of the most performed Japanese Noh plays which date to the eighth century. We saw it at two different rare-plant nurseries for the first time, so it must have just been introduced. We won't know its ultimate height until we grow it out here. It might have been kept low to make it more appealing to the customers. The director of the Des Moines, IA, botanical garden said that it has proven to be one of their best performing perennials. We have found many plants in Japan which were labeled "dwarf," but when grown out in our Deep South heat with our hot nights, a so-called dwarf plant will reach head high. It was labeled with the unknown species epithet of "sp."
