What seeds would you give as a gift to someone who is going to sell his/her belongings, and start a travel adventure around the country for a year?

The idea is that he/she could plant the seeds in different places, leaving something behind. I'm looking for any kinds of fruit/vegetable that would germinate in a variety of conditions (this will be in Australia).

I'm sorry if the question is naive or poorly phrased, I now next to nothing about gardening and flowers... this is just an idea I'm exploring.

Thank you!

Edit: I'm not asking about personal preferences or esthetics, but for facts about which seeds would have a better chance of germinating in a wide variety of conditions, as one would expect in the typical Australia weather.
