This visually arresting Greens & Radicchio Container Garden offers a delightful range of colors, textures, and shapes. Crinkly dark green kale, brightly colored chard, and richly hued radicchio can be eaten together in a salad, or separately in a variety of delicious dishes. The petunias add another shot of vibrant color to the mix. We’ve spaced these cool-weather plants a bit closer than usual to allow for a bigger harvest, so you’ll want to pick often to keep the plants from outgrowing their space. Plant them all together in a whiskey barrel, large metal tub, or other 24-inch (or larger) container with plenty of drainage (add holes if you need to).
