Flowering cabbage and flowering kale are attractive relatives of the standard varieties. Lettuce is available in a variety of colors and leaf textures. Red chard is another popular container plant because of its bright red stalks. Many gardeners like to have herbs growing near the kitchen where they are handy to use in cooking. Basil, chives, marjoram, and thyme are all easy to grow in containers.
