A: I can’t tell you about zone 6 but in zone 10 it’s grown 2 ft in 1 year
A: It's a southern tree. It says in their description it's for zones 7-10. Illinois might be too cold for it. You'd have to cover it in the winter for sure.
A: My experience with Magnolias is that they don't do well in climates that are very cold, or stay cold. I had one in Georgia, we got cold one year with snow that lasted several weeks, it died. I am not an expert, and I don't know Castle Rock, but if it's like most of Colorado that I know, it gets very cold! The plant is cheap enough to give it a try, I suppose, but I would expect problems in a cold climate.
A: You apparently know what will survive in your area, good on you! HD doesn't know and likely doesn't care what happens if you buy a plant for an incompatable region. Besides, you may want it for an indoor plant or have a greenhouse. Would you be happier if HD told you what you could or could not buy?
