Ars Nouveau has a farming mechanic (Sylph charm) where you plant a crop, and it generates the products automatically, without breaking or affecting the plant. However some crops are incompatible, the melon/squash blocks, and cumin/quinoa/sunflowers. I'm guessing cumin/quinoa/sunflowers don't work due to the output being 'seeds'.
