While I am NOT a gardener or whatever you call those people that study plants. I saw an idea from Craftopia that might work in our voxel game.
If you slay a bird or specific mobs, you can obtain a plant seed (Usually a basic one) and plant these in plantation blocks. One plant seed bag can be placed onto 4 plantation squares for 9 plants per square. Once you harvest the plants, you can research, cook, or store the plants.
Researching seeds can help progress yourself into higher tiers of plants via research but this costs gold and lots of it to do so. Its a risk vs reward but in the end…its well worth it.
Each plant has its own stats that can be combined with other plants/veggies/cooking ingredient for food.
