Find a signature plant that’s big, fast and reliable to grow each year wherever you find yourself. That way, it’s your garden (not the actual plant) that’s always with you. I love runner beans for this purpose: They’re easy to grow in a container, can twine up a support taller than you long before the season is up, can fill a corner with leafy jungle-ness and – bonus – you get a crop of deliciousness.
