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 was surprised to find 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. According to my Lois Hole books which are my plant Bibles, the only two magnolias which are good for this zone are Star Magnolia and Merrill Magnolia and even they require winter protection. Could Lois Hole really be wrong? Or could this be a misprint in the company's on-line catalogue? As much as I would love to have a saucer magnolia, I don't want to spend a bunch of money on something that will not grow and bloom for me.
