Dear friends, No one has mentioned A. psitticina, the only species to be reliably hardy and return in my climate. None of the 'so called' hardy named cvs has lasted more than a year or two, but I have not tried A. aurea. Maybe all those people pulling these up might pass them on to Dell for the Bulb X.
