Suggestions, hmmm flowered vines?
Vine covered fences?
More herbs to complete the herb family the game already has.
Iris, Marigold, Daisies, Foxgloves, Cowslip, Peony and Snowdrop. Herbs had significant usage in the Middle Ages. https://blog.english-heritage.org.uk/grow-medieval-herb-garden/ Some cool blog with pictures to help you if you are interested.
As for animals Beavers, Weasels and the Barnacle Goose.
All these are just suggestions
Really loving this game and community so far!
Thought of this last second, flowered lily pads!
