I love late flowering Magnolias; they are much more likely to avoid the spring destruction. For description and pic go to http://www.magnoliastore.com/ and hit the Collection tab at the top.

Small tree with narrow leaves has white flowers in late spring. Zone 5. For description and pic go to http://www.magnoliastore.com/ and hit the Collection tab at the top.

Like most sargenteanas this tree has large pink flowers, grows large and is not very hardy. for pic: http://www.eisenhut.ch/plant_en.php?id=137959

I’ve had M globosa growing in my scionblock for many years. It is only about 8′ tall and as wide. The flowers are fragrant and hang like eggs, barely opening, but the leaves are much more interesting. They are think and shiny and rough on top with a brown indumentum. This is not a hardy tree however. Maybe zone 7 is as low as it will go. For description and pic go to http://www.magnoliastore.com/ and hit the Collection tab at the top.
