Magnolia trees

Fifty Lakes, MN(Zone 3b)

I spent a week in Harrisburg area of Pennsylvania and was completely enamored with the magnolia trees there. I live in zone border of zone 4 and 3 and wonder if there is any species that has been hardy to my area. Anybody know?

Star Magnolia (M. stellata) is generally regarded as the hardiest Magnolia and worth a try. The cultivar 'Royal Star' is the one that is most often grown in the upper midwest. They're actually pretty common most nurseries carry them. Even if you can keep it alive over winter, these are heartbreakers with their mid April flowers often wiped out by a rogue freeze. A couple of others from the Loebner group are 'Merrill' and Leonard Messell'. I've been growing the former for several years without a hitch. Flowering has been spectacular the past couple of years, but certainly not something you can count on. They're vigorous plants and flower at a very young age. If you can find a protected site (east side of building is good) you might be able to pull it off. Good luck!

Thanks for the response. I've read that the longer you can put off their blooming the better in cooler climates.

You could also grow the North American native Magnolia acuminata there.
