want to breed a willow tree!

[Demonancer]

By far my favorite tree ever, but i cant seem to breed it :c I was told its oak and birch, but i get nothing but silver lime and silver birch..

You need to combine oak and birch (or a combination of either with silver lime) in a damp humidity (swamp for example) biome, which also means you will need bees that can live in that biome (like marsh).

I have personally confirmed this works having gotten a sapling off the oak birch combination in a swamp, forest biome never gave me the white willow mutation despite many, many mutations.

That's odd, as my first ever tree cross breed was a Willow, in a Birch Forest biome using normal Forest and Meadow bees.
I just placed 2 of each type of vanilla tree around my bees, and left them to it.
