Can Alano sapodilla grow in a pot outside it's natural growing zone

Planning to grow a sapodilla in Colorado. Fast growing trees states I can grow it as a potted tree in our zone. I see a lot of another sapodilla growing in our zone but can only seem to find Alano trees for sale online. Of course most nursery will not have it in our area as it is not in our growing zone.

I’m not sure what that means.The plant will need to be kept inside,probably for most of the year.Also,these are trees,so they do get fairly large.
