I am looking to buy a northern belle magnolia tree and would like to know sites that have them for sale

I live near Dayton, OH and have a small front yard my home faces north. I would like to know what the expected habit of a magnolia northern belle would be here. It sounds like the tree is columnar reaching 15-25 tall and roughly 10 in diameter. Is this correct Can someone recommend a tree magnolia or other which would bloom late if it blooms and would grow to nicely fill such a space I think a 15-40 tall tree with a diameter of 15-30 and an oval or rounded habit would be great. I am open to suggestions. Most people in my neighborhood have Bradford Pear trees which look beautiful, but I like to be a little different. Thanks

Northern Belle is a cultivar of Sweetbay magnolia. It blooms in June but not like you more common Saucer magnolias that are blooming now. Is thin so it would be nice for close viewing but if you neede something full it may not work. That is the question you need to ask before making the decision. Also Amelanchier Cumulus will do well.Steve
