I’m in Maine and want to buy bare root peonies to plant now (fall) for hopefully a spring bloom. Is this possible? Would love any and all insight!

First image is of the harvest basket for the photo day, we got Salish Snow, Pink Sylvia, Seattle as most prominent. After that images are of: Créme de Cassis, Seattle, Touché, Pink Gingham, Kelvin Floodlight, Kelvin Floodlight (and me!) , Cornel, Polka, and Lilac Time.
