There is confusion to which it's either an annual or a perennial because it is only hardy to zone 9. It likes a well-drained soil with full sun, part shade. There are a few varieties of marjoram, sweet marjoram being one, wild marjoram and pot marjoram being two others. It looks like oregano-being they are in the same family. Pot marjoram has white or pink flowers.
Sweet marjoram is the most useful of the marjorams to grow.
It has a sweeter taste to it. You can infuse the leaves of marjoram for a relaxing bath and also use as a hair conditioner. Rub the leaf on your tables as a furniture polish, or break the leaves into sweet bags, and potpourris. Add to your next broiled fish dish, add it to egg salads, or add it to chili or pizza. Make a stronger juice by boiling it in water, and then make jelly using your favorite jelly recipe.
