In a container in a heated greenhouse, probably, though I have not tried.

They are cold-hardy only down to about 27 degrees.

you can grow anything here as long as you can keep it warm during winter. Really what I have learned over the last 3 or 4 years is I only need to protect my stuff fully meaning always in the greenhouse from about mid November to late February. I say fully because that seems to be the time of year were there arent enough warm sunny days in a row to justify bring things out for a while.

I grow citrus, pineapple*, mango*(seedling), plumeria, bananas*, palms, and adenium(desert rose). all in containers except for a couple bananas, basjoo is in ground. Plumeria can be put in the ground then dug up for winter storage.

I havent tried star fruit, papaya, jack fruit, etc or some of the more "exotic" types but the key is just keeping them warm with enough light and humidity.

*-havent gotten fruit from these yet but patiently waiting.

What variety of mango are you attempting to grow? Mexican or Hawai'in? I love Hawai'in mangoes, and have wanted to grow some in Oklahoma. I tried growing papaya trees for a few years, I could never get enough of them to flower at the same time to produce fruit.

Mine is just a seedling I sprouted a few years ago for fun. I know it wont produce true but its still fun to have. I was going to pick up a grafted one in florida but i ran out of room when I went plumeria shopping, LOL

a few people in the tropical fruit forum have had great success growing mango in containers and even get a decent crop of fruit.
