Plants are quite useful to the intrepid space colonist, in addition to providing food, plants also help reduce life support burden and psychological stress by adding a splash of green to all those cramped metal corridors. But what plants should the intrepid space colonist take with him to cultivate?
- Plant must either provide some sort of useful foodstuff/product or be able to produce enough oxygen to reduce life support burden significantly, though being pretty helps 8)
- Plants must, probably, be able to be adapted to microgravity conditions including near freefall environments (such as asteroid habitats)
- While not strictly necessary, plants that take up minimum space and/or can grow on various surfaces (ceilings, walls, etc. . .) are useful
So. . . What plants should the aspiring space colonist take?
Clarification: I am aware of algae to be used in life support systems and my reasoning was that yes that would be part of CELSS, indeed the main part. But additional plants could help reduce the burden on the algae. So what I'm mainly looking for is decorative but useful plants that could be spread about the colony to a) Look nice, b) Help the life support manage and c) maybe provide food or something else too. However all answers are appreciated and I thank you for contributing!
Edit: while this question does provide some useful foder, my question is oriented more towards a freefall environment and not for sustenance crops
