With its black root long being used as an herbal remedy, Echinacea can successfully be grown in a container. Some varieties can reach up to 4 feet tall and 2 feet wide, according to Clemson Cooperative Extension. While it is common to plant a combination of herbs in one container, Echinacea should be planted in a large container to provide it room for growth and proper air circulation, which will help ward off disease. With the appearance of small, daisy-like flowers, German Chamomile, is as good for tea as it is for treating diaper rashes. According to the Herb Gardening website, a mature plant will reach between 20 to 30 inches tall.
According to the Colorado State University, lavender, a popular fragrant herb, can be grown in a container with a little effort. Because lavender's root balls grow best compactly, provide a container that is no larger than one to two inches larger than the rootball. Expect a mature lavender plant to reach 1 to 3 feet tall, according to West Virginia University Extension. The spicy scent of peppermint is also a popular aromatic herb, and as the plant only reaches 2 feet in height, it is ideal as an herb container plant. Woodruff is an additional aromatic herb, that only reaches 8 inches in height.
Herbs such as thyme, rosemary, oregano, parsley and basil are ideal to create Italian-inspired cuisine. According to West Virginia University Extension, thyme reaches about 6 to 10 inches in height and is a popular choice for poultry stuffing and gumbos. Provide a generous-sized container for oregano, which can grow up to 2 feet tall. The popular herb is a go-to choice for flavoring pizzas and Italian-based sauces.
Growing herbs in containers merely to enjoy their form or appearance present another possibility for the plants. West Virginia University Extension points out that herbs with variegated leaves such as mint, thyme and lavender are good options for ornamental herbs.
