While regular crop seeds don’t grow in Stardew Valley’s winter on your farm, you can definitely still grow the foraged items. These include Snow Yam, Crocus, Crystal Fruit, and Winter Root. You can get 30 of these seeds for completing the winter foraging bundle for the community center, or, if you’re high enough in your foraging level, you can make the wild seeds for winter. These are, as always, random and will yield you some great coins if you farm them in bulk. Just be wary of the time constraint as they do take awhile to harvest.
