Hi, I would like to get a japanese weeping cherry tree (snow fountains) and keep it indoors. Reasons: Have no where to plant it now, but would like to have it's beauty to brighten us up, and it will not grow too big for later when we do plant it. I am in zone 3 but will be in zone 5 or 6 when we eventually plant it. Back patio window faces East and front living room faces West. Is this possible and is it okay for the tree. If no, any alternatives? Thanks for your thoughts.
