E. dubium is a little known shorter species of Joe-Pye weed native to moist soils of eastern North America. 'Baby Joe' arrives hot on the heals of 'Little Joe'. You can guess where this is going: 'Baby Joe' is even shorter measuring in at between 24 and 30 inches compared with 'Little Joe's' four feet. The large, dome-shaped flower heads hold masses of lavender flowers which are real butterfly magnets. If you don't yet know the Joe-Pye weeds, here's an excellent place to start. Tolerant of light shade.
Moist soils in open areas.
