Willow Forest

The willow forest has only willow trees spawn in them. The biome color is very close to the color of the forest, just a little darker green, and the water more darker blue.

Generations
Like a normal forest, it generates grass on the top block, and dirt as the filler. Flowers and tall grass also generate. Mobs can spawn here, passive and hostile. The color is a little darker green than what the normal forest is. Lakes can also generate.

And of course the willow tree generates here. This is the only biome where you can get willow wood.
