A grandiflora will not flower at 2m tall. My grandiflora Exmouth is 25 year old and has been flowering sporadically through the last ten summers. It is as tall as the house and the flowers can be seen from the upstairs bedroom window.keep the surface roots well mulched with well rotted compost or farm yard manure.
A much better magnolia for a small garden is M. Soulangeana . Try the garden centres. They will have them in big tubs already in flower. My soulangeana has flowered regularly from about three year old.
