Sometimes you happily walk in the forest picking blueberries.
However, it may be that your perc*exp is too low to see them all.
But how do you know this? You don't! The forest also seems very empty if you don't see the things.
But its not like they would not exist?? You just cannot recognize them
One should be able to see generic forageable objects that they cannot usually see.
Tis' only realistic to see something that resembles a plant, even if you cannot figure out that its a blueberry.
So instead of blueberry that you can pick you would just see a "plant" object that you couldn't interact with (or possibly you could pick it to make it disappear, maybe you could pick it to get a message like "this plant resembles a blueberry but you're not too sure" if you've discovered blueberry, or then "this plant is some unknown plant" if you haven't discovered blueberry yet).
