I am new to these forums and am hoping someone will have some advice for me. I live in a zone 3b/zone 4 area and have been researching to find a large shrub or small tree for a corner of my yard. Recently, I saw that a plant nursery in the lower mainland sells two kinds of Magnolia trees that they list as being good for zone 3. One was a Magnolia (Saucer Magnolia or Tulip Tree) x soulangeana which I would dearly love to have in my yard. However, I have read in other places that these are not good in anything less than a zone 5. Could this be a misprint in the company's on-line catalogue or is it really possible that I could grow this here?
