Our mushrooms are a two part process where the base is molded into the head of the mushroom to make it as if it were one piece. We incorporate other items into the piece like rocks, pieces of wood and small twigs and faux moss. They are usually not painted but can be. They stand from about 6 inches to 24 inches tall. Although here again they can be made to whatever size you like. They tend to look exceptionally well when they are in a group of three small medium large. We also put the same mushroom in fountain.
