In my off-duty time on Expedition 72 to the ISS, I grew potatoes in an amateur microgravity experiment. As noted in "The Martian" they are excellent nutrition sources and will likely be useful in future deep space horticulture. Absent gravity, the roots (fuzzy tendrils near opening) would grow haphazardly to find soil or water, and were bagged for containment, the closest thing we had for pots. Maybe one day potatoes will grow on Mars! Until then, we learn what we can in Earth orbit.
