Cannot get a red birch tree!

[Nowaha]

I put down 2 birch trees, both with selective breeding set to red, and the trees that they breed are not red. I cannot get the Red Maple Tree :/

(see edit) I found this very interesting so I tested it. I created a new grasslands in the corner of my world. And I put down 4 birch trees all set to breed selectively with red. And the only green brich trees respawn. So you are right. you cannot get red birch trees.

[EDIT]: I coulnd't get red birch trees from the orgional birch trees. But the green trees that should have been red are able to spawn red birch trees. So you can in fact get red birch trees.
