The Black Berry Clone is a clipping of the black berry plant.
At present, the black berry provides little to no substantial use in RUST, and there is little point in producing Black Berry Clones because of this.
Like all clone plants, you can plant the black berry clone instead of Black Berry Seeds.
Planting the black berry clone will carry over the genetic line of the black berry shrub that the clone came from instead of the randomly assigned genetics of black berry seeds.
