About Marjoram

Marjoram is oregano's sweeter, milder cousin — a tender perennial herb (grown as an annual in cold zones) with a warm, aromatic flavor perfect for Mediterranean cooking.

Start indoors 6-8 weeks before last frost. Pinch regularly to keep bushy. Harvest before it flowers for best flavor. Bring pots indoors in cold zones.
