Plains

The plains is a mild, grasslands-like biome. It is among one of the first biomes added to the game. It has only one variant.

Description
Plains are mostly flat, with only limited, gradual changes in elevation. The surface is covered in tall grass. Oak trees rarely generate in the plains, and are the only source of wood in this biome apart from villages. Some patches of plains can grow various colors of tulips, and these patches (along with flower forests) are the only places where tulips may generate. In addition to the tulips, oxeye daisies and azure bluets may sporadically generate within the plains.

Villages that generate in plains biomes are made mostly of oak planks and logs, and other villages across the world default to this plains style if their wells are generated in unusual biomes, such as rivers. Horses can spawn in plains biomes, and (along with savanna biomes) is the only place where horses can spawn.

Despite the relative calmness, survival in plains biomes can be a bit tricky due to the relative sparseness of the biome, though villages can serve as a temporary refuge if one is found. Oak trees only rarely generate, making wood scarce should one not want to tear down village houses for wood. Additionally, the massive amounts of tall grass can prove to be a nuisance when building a shelter or when fighting hostile mobs. However, tamed horses can serve as a method of fast travel, allowing players to more efficiently explore their surroundings for more resources.

Variants
Plains biomes only have one variant, for a total of two different plains biomes.

Sunflower Plains
Typically found in large patches within regular plains, the Sunflower Plains variant features large numbers of sunflowers across its landscape, and is the only place where sunflowers may generate. The sunflowers make for a good source of yellow dye and a makeshift compass, as they always face east. The terrain is otherwise no different from the regular plains biome, and horses will still spawn here, though villages will not generate.

Trivia

 * The plains biome also generates in patches within Dark Forest biomes, similar to how 'Hills' biomes generate within their respective base biomes.
 * It also generates as a separation when a swamp biome generates alongside a desert.
