More Seeds [1.20.1]

[LenKagamine]

Variant species of one type of tree usually have their own seed, like the Dark Oak Poplar, but others, like the Sparse Oak, do not have their own seed, meaning that tree type cannot be grown by the player. I'm not sure of the whole list, but I know the Sparse and and I think a tree called the 'Twisty Birch' do not have their own seeds.
