Biome for World Generator

Hi, guys, how are you?
I am making a simple world generator and would like to have a notion of how I can make biomas, the main objective would be to put different textures on the map?
Anyone have any suggestions?
thankful!

Oh yeah, just to emphasize the terrain's shape are in hexagons.

Thank for all.

I apologize, because I did not express myself correctly.
In my case, my terrain will be a plan, I only need to modify the textures, I have no intention of making mountains or plains.
I would only really like to change the textures in certain parts, like biomes.

 

Look further in Catlike's tutorial-series. He has what you're looking for. Both biomes and texture manipulation/vertex painting.
