Unlike pots, planters tend to get used outdoors. Both types of plant holders can have drainage holes to ensure plant health, though some sellers use “pot” to indicate a lack of drainage. As discussed above, planters generally hold an assortment of plants. Think of the huge concrete tubs or wooden barrels stuffed with pansies or hens and chicks. In the broadest sense, a planter is any container holding a plant outside the ground. Examples include: Hanging baskets Wooden or concrete tubs Small clay or ceramic pots Raised containers of metal or rattan Resin or plastic pots Cachepots (decorative planters)
