Collards, a Southern favorite that is becoming increasingly popular in other parts of the country, take center stage in this vibrant cool-weather Herbs, Color & Collards Container Garden design. Mint and parsley add more texture and shades of green, and the marigolds deliver sunny color along the border. Be sure to plant the sweet mint (or whichever kind of mint you choose) in a smaller pot before adding it to the design, to keep it from taking over the container and crowding out its neighbors. These plants are spaced closer than they would be in an in-ground garden, so be sure to harvest the collards and herbs regularly. House them all in a whiskey barrel, or use a large metal tub or other 24-inch (or larger) container with ample drainage.
