408 · Sweet Marjoram

About this plant

Sweet marjoram is oregano's gentler relation — warm, sweet and faintly piney, and far better used fresh at the end of cooking than boiled. In our zone 9b winters it usually survives as a true perennial rather than an annual. Keep it pinched and it stays a neat, silvery mound.

Planting it at home
