Description (From Recipaedia)
Grass grows on dirt blocks when there is enough sunlight and near grass blocks are available. When conditions are right, various flowers, tall grass blades and vegetables will grow on it. Grass is easily destroyed by covering it with something heavy and takes a long time to regrow. Grass block is not obtainable except in Creative mode . When grass is broken, it drops dirt.
Notes
- Grass can be slept on.
