I am now in the third year of my plant that is now about 4 feet tall. It started as a very small plant (12 inches) and has grown very well, problem is I have yet to see a single bloom. Maybe I have not had it long enough yet....but it is supposed to be a "early" as in young bloomer.

The advantage of this magnolia is the fact that it blooms well after the leaves are unfurled, therefore no risk of late frosts spoiling the flowers. The blooms are somewhat pendant, about 4-5 inches across and highly fragrant. The red-pink stamens are also very showy. The foliage is much nicer than the spring-blooming magnolias, making it an attractive shrub throughout the entire summer. It is also among the hardiest magnolias, even surviving in zone 4 if sheltered.
