Thanks to all who offered suggestions on this plant. I am fairly sure
it is some form of Gardenia, but not taitensis since that is more of a
tropical and this plant seems to thrive in our zone 7 climate
including overnight lows below 20 in NC.
I plan to move these trees to better places in the yard this fall.
Growing trees from seeds is fun, but make sure you keep good records
so you don't forget what they are, like I did!
