I might not know the technical term for a plant with multiple generations in a year.  But I now know achaeophyte!  That's an organism, like sheperd's-purse, that was pre-historically introduced to an area by humans.  This was an Old World food plant back into pre-historical time.   Or how about protoparasitic?  The seeds of shepher'd-purse produce mucilage.  There is a hypothesis that this traps bugs in the seeds, which then provide nutrients when they germinate.  It might help explain why shepherd's-purse is so successful in environments like the one shown here.  And at times like that.  These mature plants were in Grand Rapids, Ohio, on April 20.
