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, foilage, tree houses, and in pre-glass times, windows. In Survival mode, Indev and Infdev, leaves cannot be obtained. Busting leaves will instead drop Saplings which will allow the player to plant a new tree in exchange for taking down the present one. In Indev and Infdev however, if the trunk of a tree is taken, the leaves will automaticly delete themselves, dropping saplings in the process. Leaves are very weak blocks, they will blow up in an explosion and are flammable.

Trivia

 * Leaves were used as windows before Glass was implemented.
