Leaves

Leaves are a type of block. They are very abundant in normally generated servers, appearing on every Tree. Leaves have one face which is put on all 6 sides of the block.

Leaves are available for use in Creative mode. They are often used in making plants, foliage, and tree houses. Leaves are very weak blocks, they will blow up in an explosion and are flammable.

In Survival mode, Indev, Infdev, and Alpha, leaves cannot be obtained. Busting leaves will instead sometimes drop Saplings which will allow the player to plant a new tree. If the trunk of a tree is destroyed, the leaves will disappear over time, dropping saplings in the process.

Trivia

 * Leaves were used as windows before Glass was implemented.
 * In Alpha, although Torches can be placed on leaves when using fast graphics, they cannot when using fancy graphics. Torches placed on leaves while using fast graphics will remain on leaves even if you switch graphics modes.
