Flower Pot

A flower pot is a decorative block that can contain a plant or a mushroom.

Obtaining
Flower pots can be mined using any tool, or without a tool.

A flower pot will also drop itself as an item (any plant or mushroom in it separately) when pushed by a piston or washed away with water.

Natural generation
Flower pots naturally generate in witch huts where they contain a red mushroom, the basement of igloos where they contain a cactus and in woodland mansions.

Usage
A flower pot can be used to hold mushrooms and various plants. Plants that can be in a pot include any one block high flowers, saplings, ferns, dead bushes, cacti and bamboo.

Flower pots can be placed against any surface in Java Edition.

In Bedrock Edition, they must be placed on top of a full-block top surface, or the top of a fence, stone wall or hopper. They cannot be placed on slabs and stairs unless those blocks are upside-down.

Flower pots are $3/8$ of a block high and can be stepped on. It is not possible to walk from the top of a flower pot onto a full sized block without jumping. It is possible to jump from a flower pot onto a fence. The plant or mushroom can be removed from the flower pot by pressing the control.

Trivia

 * The flower pot is based on a suggestion from Reddit, like ender chests and item frames.
 * When placed in a flower pot, cacti will not harm the player or destroy items.
 * Flower pots break falling sand and gravel blocks.
 * When aiming at the side of a transparent block behind or above a crafting table the pot will not be placed on said block but on top of the crafting table instead.
