The CobraCo Black Canterbury Horse Trough Planter has a classic style for a reason. Once you get some soil and a few of your favorite plants in there, you'll wonder how you ever lived without this versatile piece. An adjustable bracket lets you mount it on a ledge, railing, or window sill that has a width of two to six inches. The all-weather metal body has a textured finish in jet black that gives it the look of vintage wrought iron. A 24-inch coco liner fills the trough and is tough enough to hold any type of soil while still allowing for ample drainage. The biodegradable liners are eco-friendly, and don't worry, this 24-inch liner is a standard size, so you can purchase a replacement at almost any store that sells gardening supplies.
