Dead Bush

Dead Shrubs are not a solid block, but rather an aesthetic weed that does not block movements, like Sugar Cane, Wheat and Tall Grass.

Dead shrubs will only spawn on Sand blocks in desert biomes, and do not produce any resources when broken. They will only spawn in chunks generated after 1.6 is installed.

History
Dead shrubs where added to Minecraft in the Beta 1.6 update.

Trivia

 * Dead Shrubs can only be obtained by using an Inventory Editor.
 * Dead Shrubs do not produce any useful resource, and this will most likely stay the case.
 * The dead shrub texture is the sapling texture, with its leaves removed.
 * a variant of Tall Grass is visually identical to Dead Shrubs, but will be able to give seeds. however, this version of tall grass is non-naturally-occurring, and can only be invedited into the game.
