I was curious if anyone knew a container friendly mango variety? I would really love to grow them. I currently have a seed growing, from an unknown variety. I was told there are mangos that grow to be 6ft tall at their highest and very suitable for containers, but I've yet to find the name of the variety and info if they are tasty

You can look up Julie Mango. They're quite expensive to ship. Truly a natural dwarf mango:

Other dwarf mangoes include Hawaiian, Condo, and Holiday Mangoes.

Here's a decent source of mangoes that are willing to ship:
