Notes

Fruit - raw or cooked[1]. The fruit must be fully ripe before it can be enjoyed raw, if even slightly under-ripe it will be quite astringent[K]. The fruit is about 10mm long and contains a single large seed[K, 275]. Seed - raw or cooked. It can be eaten with the fruit though the seed case is rather fibrous[K].

There are no material uses listed for Elaeagnus yoshinoi.

Medicinal uses(Warning!)

The fruit of many members of this genus is a very rich source of vitamins and minerals, especially in vitamins A, C and E, flavanoids and other bio-active compounds. It is also a fairly good source of essential fatty acids, which is fairly unusual for a fruit. It is being investigated as a food that is capable of reducing the incidence of cancer and also as a means of halting or reversing the growth of cancers[2].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[3]. It should germinate in late winter or early spring, though it may take 18 months[K]. Stored seed can be very slow to germinate, often taking more than 18 months. A warm stratification for 4 weeks followed by 12 weeks cold stratification can help[4]. The seed usually (eventually) germinates quite well[3]. Prick out the seedlings into individual pot as soon as they are large enough to handle and plant out when they are at least 15cm tall.

Cuttings of half-ripe wood, 7 - 10cm with a heel, July/August in a frame. Cuttings of mature wood of the current year's growth, 10 - 12cm with a heel, October/November in a frame[5]. The cuttings are rather slow and difficult to root, leave them for 12 months[6].

Layering in September/October. Takes 12 months[3].

Cultivation

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. The plant is endemic to Japan, where it is very rare, and is included in the 1997 IUCN Red List of Threatened Plants. The following notes are based on the general needs of the genus.

Succeeds in most soils that are well-drained[7][5]. Prefers a soil that is only moderately fertile, succeeding in poor soils and in dry soils[7][5]. Established plants are drought resistant. This species is notably resistant to honey fungus[8][5].

This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[5]. An excellent companion plant, when grown in orchards it can increase yields from the fruit trees by up to 10%.
