Shrub of Sprouting

The Shrub of Sprouting is a plant from the Witchery mod. These are trapped shrubs, and look identical to normal dead bushes. When an entity walks over this plant, the plant will turn into a 10 block high tree, with a few leaf blocks of the according wood. The tree grown is random. The plant is consumed whenever an entity walks over it. The Shrub of Sprouting can only be harvested by breaking the block it is on top of, which can only be dirt, grass, or sand.
