From what I've read, they'll bloom in late spring to summer. We haven't seen them in bloom yet, but I'm anticipating quite a show.
The magnolia is the official tree/flower of Mississippi, where I lived for six years. It's even on the license plates and all the "Welcome to Mississippi" signs.
In Alabama, we are less bold about our state flower, the also-evergreen camellia. Our state flower was the goldenrod until 1959, when it was changed to the camellia. I can't argue with that choice; the camellia is one of my all-time favorite plants. It beats roses any day and even - gasp - magnolias.
I'm not overly interested in gardening and know even less about it than I do about fine wines and the proper usage techniques for Clorox bleach. All I know is I want some camellias. Also, some Confederate roses. Then I'll have a trifecta of Southern plants.
All I'll need then is a big straw hat.
