Question
Do any magnolias have slightly toothed leaves?  My tree is about 8 feet tall and has 6 inch, stiff, glossy leaves.  It has never bloomed in the 5 years I have lived with it but that may be due to lack of fertilizer or maybe it's not a magnolia.  But the leaf is quite similar to the grandiflora planted in the yard.

Answer
Sounds like maybe Frazer magnolia the leaves have a slight wavy edge to them. The tree is still young and this is the reason it has not bloomed as yet. I would fertilize it with 13-13-13 fertilizer and this should help it flower sooner.
