Dead Bush

Dead Bushes(aka Shrubs) are not a solid block, but rather an aesthetic weed that does not obstruct movement, similar to Sugar Cane, Wheat and Tall Grass.

Dead Bushes will only spawn on Sand blocks in desert biomes and rarely in swamp biomes.

Uses
The only current use for this item is decoration. It is automatically available to place while in creative mode. As of snapshot 12w05a, Dead Bushes can be picked up using shears.

History
Dead Bushes were added in the Beta 1.6 update. In the Beta 1.8 pre-release 1 update, they were placeable in creative mode and as of the Beta 1.8 pre-release 2 update they have an official name. Dead Bushes could be obtained by mining with an axe with the Silk Touch enchantment in Beta 1.9, but this was no longer possible in Minecraft 1.0. In 1.2, they could again be obtained with shears.

Trivia

 * The dead bush texture is the sapling texture, with its leaves removed and slightly modified.
 * A variant of Tall Grass is visually identical to Dead Bushes but is able to give seeds and has an offset from the ground, like tall grass.
 * If the block below the Dead Bush is removed, the bush will disappear without dropping anything.
