Tree grow animation

Is it possible to make almost realistic tree grow animation ? Using sapling or something like that ?

If you want to take the time the animall adon you can get as real as your skill will let you. I have used it with some kinda high resolution/ high poly count. To have the mesh come from nothing scale verts to zero. http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Animation/AnimAll
