My apologies for the double post. My brain is fuzzy from this cold.

I'll see your zucchini and raise you blackberries! :-)

In a hard SF novel I'm working on, people planning a colony on another world joke that if they want to terraform it quickly they can just plant blackberries, dandelions and kudzu. :-) I may have to add zucchini. Any other suggestions? (Needs to be something both fast growing and edible.)
