Physical Characteristics
 icon of manicon of lolypop
Maclura pomifera is a deciduous Tree growing to 15 m (49ft) by 12 m (39ft) at a medium rate.
It is hardy to zone (UK) 5 and is not frost tender. It is in flower from May to June, and the seeds ripen from Sep to December. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required)The plant is not self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil. The plant can tolerate maritime exposure.

Synonyms
M. aurantiaca. Toxylon pommifera.

Habitats
Woodland Garden Canopy; Secondary; Sunny Edge; Hedge;
Edible Uses
One report suggests that the fruit is edible[74] but this is surely a mistake - although very large, the fruit is harsh, hard, dry and astringent. The fruit does, however, contain an anti-oxidant which can be used as a food preservative, especially for oils[61]. The heartwood and the root yield a non-toxic antibiotic that is useful as a food preservative[240].
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.

Cardiac;  Ophthalmic.

A tea made from the roots has been used as a wash for sore eyes[222, 257]. The inedible fruits contain antioxidant and fungicidal compounds[222]. A 10% aqueous infusion and an extract diluted 1:1 have cardiovascular potentialities[240].
Other Uses
Dye;  Fuel;  Hedge;  Hedge;  Preservative;  Repellent;  Shelterbelt;  Tannin;  Wood.

A yellow dye is obtained from the bark of the root and the wood[46, 57, 95, 149, 169, 257]. Green and orange can also be obtained from it[168]. The sap of the fruit is used as an insect repellent[95]. It is said to be effective against cockroaches[222]. The bark is a source of tannin[82, 149]. The plant is often grown as a hedge in N. America and Europe[1, 20, 50], it is very tolerant of severe pruning[200], makes an effective stock-proof barrier[200] and succeeds in maritime exposure[K]. A hedge in a very exposed position at Rosewarne in N. Cornwall has grown well (1989), though it is very bare in winter[K]. This species is also used in shelterbelt plantings[200]. Wood - coarse-grained, exceedingly hard, heavy, flexible, very strong, very durable, silky, lustrous. It weighs 48lb per cubic foot. One of the most durable woods in N. America, it is seldom used commercially, but is used locally for fence posts,piers, bows etc and makes an excellent fuel[46, 82, 95, 171, 200, 227, 229, 274].
Cultivation details
Agroforestry Services: Living fence;  Fodder: Insect;  Industrial Crop: Biomass;  Industrial Crop: Dye;  Industrial Crop: Starch;  Management: Coppice;  Management: Standard;  Regional Crop;  Staple Crop: Protein-oil.

Landscape Uses:Firewood, Pest tolerant, Aggressive surface roots possible. Prefers a well-drained soil in full sun[200]. Succeeds in poor soils and also in dry ones[20]. Plants are fairly tolerant of maritime exposure[K]. They dislike waterlogged soils[188]. Dormant mature plants are hardy to about -20°c though the young growth in spring can be cut back by late frosts[200] and young plants can be damaged in cold winters[188]. Plants require hot summers to fully ripen their wood if they are to thrive in areas with cold winters[188]. Plants are tolerant of severe pruning[200]. This species is notably resistant to honey fungus[200]. Dioecious. Male and female plants must be grown if seed is required. Special Features:North American native, All or parts of this plant are poisonous, Inconspicuous flowers or blooms.
Propagation
Seed - best sown as soon as it is ripe in pots in a cold frame. Pre-soak stored seed for 48 hours in warm water and stratify for 2 months at 4°c then sow in a cold frame[113, 200]. Germination is normally good. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. The seed stores for 3 years[113]. If growing larger quantities of plants, it is probably best to sow the seed in an open seed bed[200]. Grow the plants on for a couple of years in the seed bed before planting them out into their permanent positions. Cuttings of half-ripe wood, July/August in a frame[200]. Cuttings of mature wood, November to January in a frame[113]. Layering in summer[200]. Root cuttings 4cm long in December. Plant horizontally in pots in a greenhouse and plant out as soon as possible. Good percentage[78].

I have just discovered the osage orange in my back yard a week ago. I live in Upstate New York (Utica). So I am finding this "hedge" very interesting. I have lived here for 8 years and this is the first time I have seen the osage orange. I'm amazed that it is growing in my area. Why is that?

There is a good stand of Osage Orange trees in Shreveport, LA, along the "Kings Highway Bayou". Most sources give the original range of the Osage Orange as "East Texas and Southwestern Arkansas and southern Oklahoma", but I was wondering if these trees could be original, as Shreveport is near the texas border. Another factor that makes me wonder is that this bayou (I believe) was at one time the bed of the Red River, and although the Osage Indians are credited with making bows from the wood, could not the Caddo Indians also have used the tree? I would welcome information on this from anyone, my e-mail is billandbonnie@peoplepc.com

I'm in Western Kansas and just found out about Osage Oranges as bug repellent. The instructions I received were to take each carefully picked ball, treat gently and place on a small (foam) plate[to catch any 'sap' that might leak out] and place in the corners of rooms. So far this has worked beautifully against the usual fall invasion of crickets - they are all gone! Dunno about against roaches, don't have any of those; but it would seem worth a try.

It is dry and fairly alkaline here. Zone 5, almost 4. Very hot in summer and can be quite cold in winter.

My family has lived in Kansas for 7 generations and Osage orange wood (hedge) was used a great deal on the old farmsteads. Besides the windbreaks the tree provides, the wood was used for posts, heating the house, cooking and for making wagon parts. My grandfather made many wagon tongues and single trees from hedge. Hedge should only be used in a wood burning or coal burning stove..not a fireplace. After hedge has burned down to a bed of coals, it can produce a shower of sparks like a fireworks display. Many a home has burned down from using hedge to heat.

Hedge posts can last over a hundred years in the Kansas sod. I have collected barbed wire patented in the 1800's still attached to their hedge post.

On a recent September trip to the University of Arkansas, I was amazed to see the huge lime green fruit on the trees. When I asked some people on campus what there were, I was told they were calles "horse apples". Two people told me that horse apples could be used as a bug repellant and that they put them in their attic. My curiosity about this strange fruit (and tree) brought me to the internet to learn more. I was suprised to find out that Maclura pomifera has both male and female trees. Some websites that were helpful in my search to learn more about Osage Oranges (Horse Apples) are the following: http://plants.usda.gov/java/profile?symbol=MAPO and http://hort.ufl.edu/trees/MACPOMA.pdf#search=%22Maclura%20pomifera%22

The seeds of Maclura pomifers contain a carbohydrate recognizing lectin that has been the subject of numerous reports in journals and books regarding immunological properties.

I have just discovered the osage orange in the north west of south africa, near the botswana border. I find it a very interesting fruit and would like to know if any body ever tried to dry these fruits for use in dry arrangements.elsabe van der mescht.Johannesburg,South Africa.

They are quite excellent as a bug repellent when placed under cabinets and such. However, here in Northeastern Oklahoma we call them "hedge apples" (D. Dunn, are you sure they said 'horse' and not 'hedge'? Because horse apples are a term for horse dung...)

Planted as hedges for stock control in early european settlement in Hunter Valley, New South Wales, Australia. They have not been cut for probably 50 years but still thrive on the farm. I grew up with visitors fascinated by the strange inedible fruits. I have since found a good market for the fruits with adventurous florists in Sydney. The fruits look great piled up in bowls or urns and last for ages.
