Summary

Physical Characteristics

Origanum vulgare hirtum is a PERENNIAL growing to 0.6 m (2ft) by 0.6 m (2ft in).
See above for USDA hardiness. It is hardy to UK zone 5 and is not frost tender. It is in flower from July to September, and the seeds ripen from August to October. The species is hermaphrodite (has both male and female organs) and is pollinated by Bees, Lepidoptera (Moths & Butterflies).
It is noted for attracting wildlife.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil. The plant can tolerates strong winds but not maritime exposure.

Edible Uses

Edible Parts: Leaves
Edible Uses: Condiment

Leaves - raw or cooked as a potherb[5, 52, 183]. Oregano is an important flavouring herb in Mediterranean cookery, and is often used dried rather than fresh[238]. This sub-species has a much stronger flavour than the type[238]. The leaves are used as a flavouring for salad dressings, vegetables and legumes, and are frequently included in strongly flavoured dishes with chillies, garlic, onions etc[2, 13, 21, 27, 183, 238]. A nutritional analysis is available[218]. Much of the commercially available dried oregano does not come from this plant but from a number of different, often unrelated plants[238]. These include Lippia graveolens, L. palmeri and Origanum syriacum[238]. A herb tea is made from the dried leaves and flowering stems[183, 207, 238].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Antiseptic Antispasmodic Carminative Cholagogue Diaphoretic Emmenagogue Expectorant Stimulant
Stomachic Tonic

Oregano has been used as a culinary and medicinal herb for thousands of years. It has a beneficial effect upon the digestive and respiratory systems and is also used to promote menstruation[254]. It should not be used medicinally by pregnant women though it is perfectly safe in small amounts for culinary purposes[254]. The leaves and flowering stems are strongly antiseptic, antispasmodic, carminative, cholagogue, diaphoretic, emmenagogue, expectorant, stimulant, stomachic and mildly tonic[4, 7, 9, 21, 254]. The plant is taken internally in the treatment of colds, influenza, mild feverish illnesses, indigestion, stomach upsets and painful menstruation[238]. It is strongly sedative and should not be taken in large doses, though mild teas have a soothing effect and aid restful sleep[244]. It should not be prescribed for pregnant women[238]. Externally, oregano is used to treat bronchitis, asthma, arthritis and muscular pain[238]. The plant can be used fresh or dried - harvest the whole plant (but not the roots) in late summer to dry and store for winter use[244]. Oregano is often used in the form of an essential oil that is distilled from the flowering plant[4]. A few drops of the essential oil, put on cotton wool and placed in the hollow of an aching tooth, frequently relieves the pain of toothache[4, 207]. This plant is one of the best natural antiseptics because of its high thymol content[7]. The essential oil is used in aromatherapy to treat the same kinds of complaints that the herb is used for[238].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Other Uses

Dye Essential Repellent

An essential oil from the plant is used as a food flavouring, in soaps and perfumery[115, 171]. A red or purple dye is obtained from the flowering tops[4, 7, 13, 100], it is neither brilliant nor durable[115]. The plant repels ants[46]. A useful ground cover for sunny positions, forming a slowly spreading clump[197, K].

Cultivation details

Requires a rather dry, warm, well-drained soil in full sun, but is not fussy as to soil type, thriving on chalk[1, 27]. Prefers slightly alkaline conditions[200]. Tolerates poor soils[24]. Dislikes wet soils[37]. Often cultivated as a culinary herb, this is a sub-species from Greece, its flowers are white and it has a stronger fragrance. It is more commonly grown commercially because of its stronger fragrance. There are some named forms[183]. Plants growing near the sea have the most fragrance[7]. A good companion plant, improving the flavour of nearby plants. The flowers are very attractive to bees and butterflies[5, 30]. A good companion for the cucumber family[14], it is beneficial to all nearby plants[20]. The whole plant is strongly aromatic. Members of this genus are rarely if ever troubled by browsing deer[233]. The plant is heat tolerant in zones 10 through 2. (Plant Hardiness Zones show how well plants withstand cold winter temperatures. Plant Heat Zones show when plants would start suffering from the heat. The Plant Heat Zone map is based on the number of "heat days" experienced in a given area where the temperature climbs to over 86 degrees F (30°C). At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 (no heat days) to 12 (210 or more heat days). For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a clumper with limited spread [1-2]. The root pattern is rhizomatous with underground stems sending roots and shoots along their length [1-2].

Propagation

Seed - sow early spring at 10 - 13°c and only just cover the seed. Germination usually takes place within 2 weeks. Prick out the seedlings into individual pots when they are large enough to handle and plant them out into their permanent positions in early summer. The seed can also be sown in situ in late spring. 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.
