I don't think that will work, unless you plan on bringing the pots in for the winter and keep them around 50F at least until a leaf emerges. kelloggii seed germinates and develops and send up the first leaf, all at about 50F. In nature, they germinate in the fall and develop through their mild winter. Once they have gone through these stages, then they might adapt to our regular seasons.
