Unique Crops Mod adds 14 new crops, all unique to each other, and several new items related to them. While the crops themselves are documented in the in-game guide book well enough, the items and gear/tools that are included in this mod are left up to the user to find out what they can do. There may even be completely undocumented easter eggs, with no real indication of how to get them.
First, get some Normie seeds by breaking a few grasses in the world, then use the seed as one of the crafting ingredients to make the mod’s ingame documentation book. You will need this book with you to help figure out how to grow some crops, and how to harvest them as well. Thanks for stopping and looking!
