Sanzashi, Chinese hawthorn
Crataegus cuneata
Family: Rosaceae
What it is like
Crataegus cuneata is a deciduous Shrub growing to 15 m (49ft 3in). See above for USDA hardiness. It is hardy to UK zone 6 and is not frost tender. It is in flower from May to June. The species is hermaphrodite (has both male and female organs) and is pollinated by Midges. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils and can grow in very alkaline soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist or wet soil and can tolerate drought. The plant can tolerates strong winds but not maritime exposure. It can tolerate atmospheric pollution.

How it is used
Food
Rating: 3
Fruit - raw or cooked and used in pies, preserves etc. It can also be dried for later use. A pleasant flavour, it is sold in local markets in China and Japan. The fruit contains about 0.44% protein, 1% fat, 22.1% carbohydrate, 0.8% ash, it is rich in vitamin C, fruit acids and pectin. There are up to five fairly large seeds in the centre of the fruit, these often stick together and so the effect is of eating a cherry-like fruit with a single seed.
Medicine
Rating: 3
The fruits and flowers of hawthorns are well-known in herbal folk medicine as a heart tonic and modern research has borne out this use. The fruits and flowers have a hypotensive effect as well as acting as a direct and mild heart tonic. They are especially indicated in the treatment of weak heart combined with high blood pressure. Prolonged use is necessary for it to be efficacious. It is normally used either as a tea or a tincture. The fruit is anodyne, anticholesterolemic, antidiarrhetic, antidysenteric, astringent, blood tonic, cardiotonic, haemostatic and stomachic. It is used in the treatment of dyspepsia, stagnation of fatty food, abdominal fullness, retention of lochia, amenorrhoea, postpartum abdominal pain, hypertension and coronary heart disease.
Anodyne: Relieves pain, it is milder than an analgesic.
Anticholesterolemic: Prevents the build up of cholesterol.
Astringent: Produces contraction in living tissue, reducing the flow of secretions and discharges of blood, mucus, diarrhoea etc.
Blood tonic: Is this any different to a blood purifier?
Cardiotonic: A tonic for the heart.
Dysentery: Used in treating dysentery - an infection of the intestines that causes diarrhoea containing blood or mucus.
Haemostatic: Controls internal bleeding.
Hypotensive: Reduces blood pressure, it is used in the treatment of high blood pressure
Stomachic: Aids and improves the action of the stomach.
Vitamin C: Plants good for their vitamin C content

Wood - heavy, hard, tough, close-grained. Useful for making tool handles, mallets and other small items.
Scented Plants: Plants noted for their scent
How it is grown
A very easily grown plant, it prefers a well-drained moisture retentive loamy soil but is not at all fussy. Once established, it succeeds in excessively moist soils and also tolerates drought. It grows well on a chalk soil and also in heavy clay soils. A position in full sun is best when plants are being grown for their fruit, they also succeed in semi-shade though fruit yields and quality will be lower in such a position. Most members of this genus succeed in exposed positions, they also tolerate atmospheric pollution. Although perfectly cold-hardy in most of Britain when dormant, the young growth of this species might be susceptible to spring frosts. Hybridizes freely with other members of this genus. Seedling trees take from 5 - 8 years before they start bearing fruit, though grafted trees will often flower heavily in their third year. The flowers have a foetid smell somewhat like decaying fish. This attracts midges which are the main means of fertilization. When freshly open, the flowers have more pleasant scent with balsamic undertones. Seedlings should not be left in a seedbed for more than 2 years without being transplanted.
Propagating it: Seed - this is best sown as soon as it is ripe in the autumn in a cold frame, some of the seed will germinate in the spring, though most will probably take another year. Stored seed can be very slow and erratic to germinate, it should be warm stratified for 3 months at 15°c and then cold stratified for another 3 months at 4°c. It may still take another 18 months to germinate. Scarifying the seed before stratifying it might reduce this time. Fermenting the seed for a few days in its own pulp may also speed up the germination process. Another possibility is to harvest the seed 'green' (as soon as the embryo has fully developed but before the seedcoat hardens) and sow it immediately in a cold frame. If timed well, it can germinate in the spring. If you are only growing small quantities of plants, it is best to pot up the seedlings as soon as they are large enough to handle and grow them on in individual pots for their first year, planting them out in late spring into nursery beds or their final positions. When growing larger quantities, it might be best to sow them directly outdoors in a seedbed, but with protection from mice and other seed-eating creatures. Grow them on in the seedbed until large enough to plant out, but undercut the roots if they are to be left undisturbed for more than two years.
