Crescent-shaped concrete planters are perfect for creating the so-called “blooming walls”.  They are interesting architectonic elements that help to organize the space of the garden.  They do not have bottoms so precipitation can permeate into lower levels.  They also work as enclosures of retaining walls. Concrete planters are often used when constructing fences or hardening banks. They are available in two sizes: PICCOLO AND GRANDE.
