  Aster ageratoides Turcz. 

Aster

The Aster ageratoides complex includes a number of subspecies and varieties found in eastern Asia.  Considerable work has been done on the cytology of some of these infraspecific taxa including experimental hybridization with species of the Kalimeris group of Aster (e.g., Tara 1972, 1973, 1978, 1979, 1984, 1985, 1987, 1989).  This is not surprising because Aster ageratoides is closely related to these species of aster with a reduced pappus (Ito et al. 1995; Brouillet, Allen, Semple and Ito 2001a, b).  It can be cultivated in North America where several subspecies grow well in the garden, at least in Ontario (Semple et al. 2002).
