Berry Bush
From Super Fantasy Kingdom Official Wiki
Berry Bushes are the source for 
Berries in Super Fantasy Kingdom.
Usage
Every run there are 7 × Berry Bushes spawning naturally. Berry Bushes can be harvested by workers assigned to the 
Tavern. Once a berry bush is depleted it's gone and cannot be regrown.
Since every Berry Bush can be harvested 5 times you can get a maximum amount of 35 berries from the naturally spawned berry bushes. More can be grown by asking the gnomes to regrow them for 1 berry. Adding an additional 5 berries for a net gain of 4.
