I was searching for herbs in Kingdom Come: Deliverance when I found this little patch of Wild Garlic or Jack-in-the-Hedge. This isn't the same plant as bulb garlic, but the leaves have a garlicky taste. We're too late in the year though - once the flowers have blossomed, in late spring, the leaves become bitter.
This isn't a herb you can collect in the game. This is literally just generic forest foliage for background detail. They've used a real plant and put it in a fairly appropriate location - near water - for absolutely no reason except detail and accuracy.
That is ridiculous.
I might be the first person to ever notice or care about this.
You can buy garlic in the game, and the illustration for it is Wild Garlic leaves rather than bulb garlic, so the implication is that the peasants have been collecting this earlier in the month, when it was still good.
