This mod adds a larger flower pot made from hardened clay, and includes stained versions as well. Pots start out empty when first placed, but can be filled with a few different substrates (dirt, sand, gravel, etc). Almost any in-game plant can be put in these flower pots, including double-height plants and crops. Most mod-added plants should also be compatible. Placing pots of the same color and substrate next to each other causes them to join into a continuous planter.
In addition to pots, the mod can grow small trees in the pots and allow harvesting the wood for new decorative structures and fences. Additional minor additions may be added in the future.
