Marjoram is primarily used for culinary purposes. It is used to season a diverse range of recipes from soups and salads to meat and sauces. As of now, it has minimal medicinal purposes, including an Austrian practice of using it for digestive and gastrointestinal ailments, but is always good to have in stock in an herb garden.
To keep it growing, continuous seeding and pruning is necessary. Like most other herbs, it needs well drained medium rich soil and full sun. Medium rich soil can be found at your local greenhouse or home improvement store.
Fun Fact: Marjoram is indigenous to Cyprus and southern Turkey.
