Artichoke

Unlocks once you've harvested 380 Kidney Beans, 300 Garlic, 210 Red Bell Pepper and 50 Watermelon in all; unlocking it is then free.

A seed costs 55 spare parts and grows for 9m 13s (7m 22s on fertilized soil), needing water 8 times on the way: it stops growing until it's watered. It gives 15 harvests, growing back from scratch after each one.

Each harvest is one Artichoke and 18 spare parts: 270 from one seed, 215 more than it cost, over 2h 18m of growing. In a Biofuel Converter each one is worth 13 biofuel.

A Reaper chip can improve its grow time, watering, harvests, biofuel or earnings.
