That would most likely depend on the weather, not the forest. It's nice on rare occasions, but shouldn't be overdone.
In any case, I want forests to be lush and alive.

I guess you are right though, it is a lot more about changing weather
The above would be pushing it for a massive variation on landscape anyways.
