Description of the plant:
Habitat of the herb:Sunny places in upland wilds. Valleys, thickets and hills at elevations of 200 - 2000 metres.
Edible parts of Sanzashi: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.
Other uses of the herb:Wood - heavy, hard, tough, close-grained. Useful for making tool handles, mallets and other small items.
Propagation of Sanzashi: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.
Cultivation of the herb:Sunny places in upland wilds. Valleys, thickets and hills at elevations of 200 - 2000 metres.
