A small mod that adds craftable saplings that grow into vanilla trees, and a way to farm them. This includes a patch to make the mod work in 1.1 when bots, scripts or blueprints create planters/saplings.
Is it possible to make this work with Alien biomes' added tree variants? I realised after installing that the saplings never grow up because there are no 'vanilla' trees for them to grow into with Alien biomes installed.
