Tomatoes.

Tomatoes appear to work simple enough, until you harvest them
the first time: The plant stays! However, after the 3rd to 5th
harvest, the plant wilts and needs to be removed, since no more
tomatoes will grow on the plant. Per harvest you can get 1-2
tomatoes only. You can craft the tomatoes to tomato seeds, as
expected.
