Flowers in Minecraft

Flowers are naturally occurring Plants that come in a variety of shapes and colors - gamepedia.com

Flowers naturally generate on dirt and grass blocks. Even in a Biome covered with snow, flowers will generate naturally on dirt blocks with grass, despite the adjoining dirt blocks being covered with snow.

As an example the Oxeye Daisy does not grow in the Swamp or Forest, but it does grow on the Plains, Sunflower Plains and the Flower Forest.

You can put flowers into a Flower Pot.

Flowers in Minecraft can be instantly broken with any item (or no item). Flowers will also be broken if water runs over its location.
