When considering what kind of corn to grow in your container, you’ll want to think not only of ornamental and taste preferences but height and size as well. Since corn can cross-pollinate very easily via the wind, it’s best to stick to one variety of corn for your container. You’ll also want to choose shorter varieties that peak at 4 to 5 feet tall. Some good choices include Strawberry Popcorn, Sweet Spring Treat, Trinity, and Sweet Painted Mountian.
