The following uses are for O. majorana. They almost certainly also apply to this plant. Leaves - raw or cooked. Sweet marjoram is widely used as a flavouring for salad dressings, vegetables, legumes and oils. It has a more delicate flavour than the closely related oregano (Origanum vulgare), and is best when used fresh and only added towards the end of cooking. The aromatic seeds are used as a flavouring in sweets, drinks etc. A herb tea is made from the fresh or dried leaves. The flavour resembles a blend of thyme, rosemary and sage.

How it is grown
Requires a rather dry, warm, well-drained soil, but is not fussy as to soil type, thriving on chalk. Prefers slightly alkaline conditions. Plants are not hardy in all parts of Britain, they tolerate temperatures down to about -5°c, possibly lower if the roots are given a good mulch in the autumn. This species is probably a hybrid between sweet marjoram (O. majorana) and Oregano (O. vulgare). It resembles O. majorana in appearance and aroma, and has the same culinary uses, but is more tolerant of British winters. A good companion plant, improving the flavour of nearby plants. The flowers are very attractive to bees. Members of this genus are rarely if ever troubled by browsing deer.
Propagating it: Seed - this species is a sterile hybrid and so does not produce seed. If you wanted to grow it from seed then you would need to hybridise O. vulgare x O. majorana. The resulting seedlings would be rather variable. Division in March or October. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer. Basal cuttings of young barren shoots in June. Very easy. Harvest the shoots with plenty of underground stem when they are about 8 - 10cm above the ground. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.
