Spruce tree dropping Christmas baubles.

I had a spruce tree that was dropping Christmas baubles instead of pine cones.
It had snow on it if that matters. (Speaking of snow, I can't remember the last time it snowed in my world.)
I don't remember when I planted it.
It wasn't growing any bigger so I chopped it down to replant it.
It dropped a spruce tree. I planted it.
It is now a normal spruce tree.

How can I get my infinite Christmas bauble tree back?

What your going to need is a "Christmas tree sapling" like the one here in the picture. Not sure why yours dropped the wrong sapling probably a bug. I think you should be able to get one by making a stand alone adventure world and setting the season to winter. Then look for the gifts could take a while to get one to drop the tree you want...

Alright, thanks!
