It depends on what type of place your girlfriend going to live, is it a condo, apartment or room for rent? If your girlfriend is living on a condominium or apartment then I suggest a dwarf/bonsai fruit tree would be nice. You can actually plant a fruit tree on a pot or container and the most common dwarf fruit tree that is easy to maintain are the citrus fruit trees like lemon, orange and lime. Besides from citrus fruits, there are also dwarf mango, avocado and pears. I am not sure and I don't know if there is a for sale of dwarf fruit trees in your country. But if there is none, then you plant it your self and I suggest you start with lemons.
