(60-90 days. Origanum majorana) Sweet marjoram is a close relative of oregano, but offers a more delicate flavor to cooking. Use fresh or dried leaves in salads, dressings, meat, sausage, lamb dishes, beans and soups. It is best used fresh at the end of preparing a dish so the flavors will be enhanced and not overpowered. Grows 2 feet tall and 1-1/2 feet wide. The wiry, red-brown stems support downy, gray-green leaves up to 1-1/4 inch long. Tiny white to pink flowers are produced in clustered spikes from late summer through fall. Pinch out the top when the plant is 2-3 inches tall to encourage side growth. Perennial.
