What kind of Tulip Tree? My sister in Houston bought a 'Tulip Tree' and it's some kind of Magnolia tree. Not at all what I learned as a Tulip Tree. What I know as a Tulip Tree is Liriodendron tulipifera and it doesn't seem much like a Magnolia of any sort. To me. If it's a single tree without any other growing for miles around, perhaps it requires a pollinator in order to produce viable seeds. Do the Magnolia types grow that far north? I'm not sure how far north the range is on Liriodendron tulipifera, but it's relatively common in east Texas and in Arkansas.
