Concrete can be cast in nearly any shape and finished in nearly any color or texture, making it the perfect medium for beautiful and creative planters, pots and vessels. Concrete can be used to make vessels that accent any garden or house style. Concrete planters can be used indoors or outdoors and are made of a lightweight concrete mix. Sizes can range from tabletop pots, to large outdoor troughs. Concrete planters of varying sizes, shapes or colors can be grouped to create an attractive container garden. One of the biggest appeals to concrete pots and vessels is their earthiness and appearance as they change over time.
