Marigolds are very easy to grow and are available in a variety of colors, including white, yellow, orange, red, and mixed colors. They will bloom from mid-summer . Marigolds also come in a wide range of sizes, from miniatures smaller than a foot to giant varieties that can grow up to four feet tall! You can select the color and size that is perfect for your flower garden. And don't overlook marigolds in container gardens, as the smaller varieties do well in containers.
