The picture explains everything, it's a chart of all the main crops, their growing locations, their products, and the uses of the products. Almost every crop can be brewed into alcohol, while some can be processed into products for other industries. It does leave out the newer plants which are only found in certain biomes, but they're all covered on the wiki.>color: workshop used to make the item; refer to legend at the lower left>abcd: growing season, from spring to winter where . denotes non-growable (subterranean crops are curiously the only ones with growing seasons, oddly enough)>raw food: can be eaten as-is with no further processing>alcohol: booze, sapient creatures get cranky if they go without it for too long>ration: can be used in a kitchen to make meals, but no seeds are produced if raw foods are the input so it's best to use secondary products like flour, leaves, or syrup>thread: thread for the textile industry>dye: dye for thread and cloth, which is an optional input for the textile industry>export: not usable but a valuable extract nonetheless (gnomeblight technically can melt gnomes but it's a lot of work to set up for little purpose except cruelty)
It also leaves out rock nut oil for quarry bushes, which is used to make soap.
