A Maple Tree is a type of Tree. It grows from a Maple Seed, so long the area in a one tile radius remains clear. A properly planted Maple Seed has approximately a 20% chance of growing to the next stage each day, though Maple Trees do not grow in Winter.
If a tree or other items are directly adjacent, the tree will not grow to maturity, but halts at stage four. Once fully grown, items can be placed next to the tree without affecting it adversely.
